Blue Bandpass Filter.
Recommended for use with 470nm blue LEDs
and for UV fluorescence imaging
BP470 filters are recommended for use in most blue LED (~470nm) and many UV-excited blue fluorescence (430-500nm) imaging applications. Important for both applications is the breadth of the bandwidth. In the case of blue LEDs, frequent variations in center wavelengths and angles of incidence can easily be accommodated. BP470 ABSORBS lower wavelengths (e.g., UV) and REFLECTS longer wavelengths (e.g., 500-1150nm). This material does not auto-fluoresce.
Cyan Bandpass Filter.
Recommended for use with cyan LEDs
Our BP505 filter was designed for use with 500-510nm cyan LED lighting. It also has a function in UV fluorescence imaging of some commonly used stains.
The BP505 single substrate, hard-coated filter is designed to match the output of most cyan LEDs, widely considered to currently be the brightest "monochrome" LEDs available. Coupled with the spectral sensitivity of most CCD/CMOS sensors in use today that also peak in this range, this filter will result in images that are especially bright and very high in contrast.
The BP505 filter is particularly designed for use in line-scan/wide angle applications where they are extremely resistant to the effects of "blue shifting." Used together with the right lensing, a line of uniform end-to-end brightness can be imaged at wide angles.
Light Green Bandpass Filter.
Recommended for use with green LEDs and fluorescence imaging
BP525 filters have been designed for use in almost all green LED or laser diode applications. These single substrate, hard-coated filters also have wide application in UV fluroescence imaging of various commonly used stains and plastic materials that fluoresce in the green portion of the spectrum.
MidOpt strongly recommends our BP525 over all other widely offered green bandpass filters because of its broad passband, far higher peak transmission, far superior blocking of UV and IR wavelengths, and reduced sensitivity to angle of incidence changes. Compared to any other “green” filters offered for industrial imaging, the BP525 will nearly always result in significantly brighter and higher contrast images.
Orange Bandpass Filter.
Recommended for use with amber/orange LEDs and fluorescence imaging.
BP590 single substrate, hard-coated filters are recommended for use in systems that use amber or orange LED lighting. They are also very widely used in fluorescence imaging applications, particularly with certain inks and ethidium bromide, Qdot 605 and other similar stains.
As with all MidOpt bandpass filters, peak transmission is greater than 90%. Blocking of shorter AND longer wavelengths averages >99% when used in conjunction with any sensor that has a typical silicon response. This is particularly important in situations where infrared light may be present. Orange longpass filters have traditionally been recommended for these applications, but they offer no such IR?blocking and therefore contrast can suffer.
Light Red Bandpass Filter.
Recommended for use with red laser diodes and LEDs.
The MidOpt BP635 filter is recommended for 610-650nm LED and laser diode lighting. Because of its broad bandwidth and high peak transmission, the single substrate, hard-coated BP635 works very well for all lighting applications in this range.
Colored longpass filters have long been recommended for use with monochrome cameras to aid in increased contrast and resolution. These filters block UV and shorter visible wavelengths, and pass longer wavelengths of light. Except in those few cases where an IR blocking or other shortpass filter is incorporated into the camera or sensor, MidOpt will often recommend the use of a broad color bandpass filter (whose designs incorporate these longpass filters) over color longpass filters alone.
Dark Red Bandpass Filter.
Recommended for use with dark red LEDs
We recommended the BP660 for use with 650-680nm LED and laser diode lighting. Because of its ample bandwidth and excellent in-band transmission, it works very well for all camera-related applications in this range. We currently provide more BP660 single substrate, hard-coated filters than any other filter in our line.
Color longpass filters, sometimes referred to as "sharp cut" filters, are often suggested by others for creating increased contrast and resolution. They will block UV and shorter visible wavelengths but still pass all longer wavelengths. Except in those few cases where an IR-blocking or other shortpass filter is incorporated into the camera or sensor, MidOpt will for the most part recommend the use of one of our broad color bandpass filters (such as the BP660) over these "sharp cut" longpass filters alone. The results are consistently improved contrast in most inspection applications over the long term.
Recommended when using high-power 860-880nm infrared LED lighting or 905-920nm laser diodes, this filter also features high peak transmission and rugged coatings that provide added environmental stability.

FWHM : 130nm

Minimum Peak Transmission : >90%
Surface Quality : 40/20

MidOpt introduces the backlight FluoreSheet™ (BF590). When the FluoreSheet™ is illuminated from the front with a blue LED light, it emits an orange fluorescence. A backlight effect can be created by using a MidOpt orange Bandpass Filter (BP590) to capture the orange emission and block the blue LED excitation, giving the appearance of a bright white diffuse background in a monochrome image.
Linear Rotating Polarizer (with locking screw).
Used to eliminate glare, a linear polarizer in a rotating mount offers flexibility and ease of use. Once the filter is screwed to the lens, the outer portion of the mount rotates freely. This facilitates determining the point where reduction of glare (or the contrast in stress patterns in glass or plastic materials) is maximized. However, because the mount rotates freely, it is also possible for vibration or other inadvertent interference to cause the filter to move from this position and adversely effect the system's performance. For this reason, all MidOpt polarizers come with a locking thumbscrew to insure that jarring or accidental movement during cleaning does not result in a change in the filter's position.
Circular Polarizer.
Circular polarizers are mainly used in consumer applications, such as with camcorders or SLR cameras that have a beamsplitter that send part of the light coming through the lens to a viewfinder and part to a light meter. Light entering the exposure meter is partially polarized by the beamsplitter. A linear polarizer over the lens would act as a secondary polarizer and block light going to the meter (but not the sensor or film), resulting in incorrect exposures. A circular polarizer ovecomes this problem with the addition of a ¼-wave retarder, which rotates the linearly polarized light 90° so that it appears unpolarized to the light meter, resulting in proper exposure.
IR Linear Polarizer.
Although they will certainly transmit infrared light without any problem, visible polarizers do not work in the near infrared. MidOpt near-infrared polarizers are for use in the 850-2000nm range. The extinction ratio over this range is 1,000:1 to 10,000:1; polarizing efficiency is 99.9 to 99.99%.
Single substrate lnfrared linear polarizers are sold in rotating mounts but are also available in "fixed" mounts. Once the filter is screwed into the lens, the upper portion of the mount that contains the linear polarizer can be easily rotated to find the optimum setting.
Because the mount rotates freely, it may be possible to accidentally move the filter and adversely effect the system's performance. For this reason, MidOpt polarizers are supplied with locking thumbscrews to insure that jarring or accidental movement during cleaning does not result in a change in filter position.
Linear Polarizing Film.
Polarizing material can be cut, drilled and formed to fit most any type of lighting equipment. By placing a piece in front of a light source, then one that's able to rotate (PR032) in front of the lens, the greatest flexibility and control over the light coming into the camera is achieved.
