BP470 Blue Bandpass Filter
- threaded mount, c-mount and slip mount option
- unmounted option and different sizes available
BP470 Blue Bandpass Filter enhance viewing of subjects illuminated by blue LED lighting and any UV- excited blue fluorescence emissions (430-500nm). Its broad bandwidth and high peak (T ≥90%) transmission results in significantly brighter, higher contrast images. For most machine vision UV fluorescence applications, use of a BP470 filter is absolutely necessary. The StablEdge design prevents unwanted interference from lighting employed for UV excitation (365-405nm) even when the filter is used in conjunction with short focal length, wide angle lenses. BP470 is also frequently used in 3D measurement applications. Useful Range : 425-495nm FWHM : 85nm Tolerance : +/- 10nm Peak Transmission : ≥90% Surface Quality : 40/20 Compatible LED : 450nm, 465nm, 470nm
BP635 Light Red Bandpass Filter
- threaded mount, c-mount and slip mount option
- unmounted option and different sizes available
A BP635 Light Red Bandpass Filter is recommended for use with 615-645nm LED and laser diode lighting. Because of its broad bandwidth and high peak transmission, BP635 filters work very well for all “light red” lighting applications in this range. Useful Range : 615-645nm FWHM : 60nm Tolerance : +/- 10nm Peak Transmission : ≥90% Surface Quality : 40/20 Compatible LED : 617nm, 625nm, 630nm
BP660 Dark Red Bandpass Filter
- threaded mount, c-mount and slip mount option
- unmounted option and different sizes available
The BP660 Dark Red Bandpass Filters are recommended for use with 650-680nm LED and laser diode lighting. Because of the ample passband and excellent in-band transmission, it works well with all camera-related applications in this range. Useful Range : 640-680nm FWHM : 60nm Tolerance : +/- 10nm Peak Transmission : ≥90% Surface Quality : 40/20 Compatible LED : 660nm
BP850 Near-IR Bandpass Filter
- threaded mount, c-mount and slip mount option
- unmounted option and different sizes available
The BP850 Near-IR Bandpass Filter is recommended when using high-power 830-850nm LED or laser diode lighting to improve contrast in surveillance applications or when inspecting in the infrared, this filter features high peak transmission and particularly durable, robust coatings. This filter’s coated surface also greatly inhibits staining due to year-round issues with heat, humidity, and/or air quality that affect uncoated infrared filters. Useful Range : 820-910nm FWHM : 160nm Tolerance : +/- 10nm Peak Transmission : ≥90% Surface Quality : 40/20 Compatible LED : 840nm, 850nm
BN940 Narrow Near-IR Bandpass Filter
- threaded mount, c-mount and slip mount option
- unmounted option and different sizes available
The BN940 Narrow Near-IR Bandpass filters feature a narrow band design with improved blocking of unwanted light and greater insensitivity to short shifting, making them particularly essential when 940nm lighting is used together with a short focal length camera lens. 940nm LEDs are commonly used in remote control devices and in security/surveillance lighting. 940nm illumination is often considered “covert,” as little if any faint red glow is produced from these LEDs, even in complete darkness. Unfortunately CMOS and CCD cameras have greatly reduced sensitivity at these wavelengths, and strong ambient light can often make imaging in this range very difficult. Useful Range : 928-955nm FWHM : 55nm Tolerance : +/- 7nm Peak Transmission : ≥90% Surface Quality : 40/20 Compatible LED : 940nm
