MidOpt Bandpass Filters
MidOpt Bandpass Filters are the simplest, quickest and most cost-effective way to improve contrast, resolution, repeatability and stability in any machine vision system.

• Designed for LED Illumination to emulate and accommodate the entire output of the LED
• Standard Filter Bandwidths from 60-90nm
• All MidOpt bandpass filters are anti-reflection coated to maximize peak transmission at greater than 90%
• Shields systems from unwanted ambient light
• Essential tool to test for the optimal wavelength for any given application
• Also suitable for laser diodes and capturing UV excited fluorescence emissions
• Available in UV/Visible/Infrared wavelengths

Filters used with common LED wavelengths:
> 365nm LED = BP365 UV Bandpass
> 400nm LED = BP395 UV Bandpass
> 470nm LED = BP470 Blue Bandpass*
> 505nm LED = BP505 Cyan Bandpass*
> 520-530nm LED = BP525 Green Bandpass*
> 590nm LED = BP590 Orange Bandpass*
> 617-635nm LED = BP635 Red Bandpass*
> 660nm LED = BP660 Dark Red Bandpass
> 740nm LED = BP735 IR Bandpass
> 810nm LED = BP810 IR Bandpass
> 850nm LED = BP850 IR Bandpass
> 880nm LED = BP880 IR Bandpass
> 940nm LED = LP920 IR Longpass
* Filters also commonly used for UV fluorescence emissions
