Dual Bandpass Filter Visible (VIS) + 940nm Near-Infrared (IR) Filter - MidOpt DB940 GOYOThe MidOpt DB940 Dual Bandpass Filter Visible (VIS) + 940nm Near Infrared (IR) Filter passes VIS and reflects 940nm LED light without impacting system Modulation Transfer Function (MTF). 940nm LEDs don't emit the faint red glow associated with 850nm and other lower near IR (NIR) LED wavelengths. Using a DB940 filter over or behind the lens allows full color imaging during the day and covert surveillance at night. However, any cameras spectral response
LE010-43 10mm Extension Tube and LE005-43 5mm Extension Tube
The MidOpt Bi830 Near-Infrared (IR) Interference Bandpass Filter is recommended for use with commonly used IR LED or laser diode illuminators operating at or very close to the 830nm wavelength
The FK201 also includes a high-contrast linear polarizer filter
The Bi525 is recommended for systems that use 520nm green laser diodes or 520nm / 525nm green LED light sources
Use of a Bi750 placed filter over the camera sensor or camera’s objective lens can eliminate interfering VIS and longer wave near-IR (NIR) light in order to greatly improve contrast / detection
It's sometimes used with fiber optic lighting
multispectral
The MidOpt Bi385 Near-Ultraviolet (UV) Interference Bandpass Filter can be used together with 385nm UV LED
lightweight alternative compared to systems employing three or more cameras or sensors
Filters included in the NS100 have a surface quality of 60/40
The MidOpt SP910 Near-Infrared (IR) Dichroic Shortpass Filter is useful for passing multiple wavelengths with a broad spectrum camera
These filters are also excellent for use in vegetative health monitoring applications where separate blue plus near-IR imaging sensors / cameras are used as opposed to the more traditional NDVI index applications that utilize red plus near-IR wavelengths
