532nm 650nm 808nm  850nm 940nm Narrow Bandpass Interference Optical Filter

Bandpass filters transmit light only within a defined spectral band ranging from less than one to many nanometers wide.It's preferable to monochromators because of their higher transmission and better signal-to-noise. 

Technical Specifications:

  Note for Interference Filter:
(1). Custom-made diameter is available, Custom-made shape of interference filter is available.
(2). Typical thickness is from 2.0mm to 5.0mm, custom-made thickness from 2.0mm to 10.0mm is available.
(3). Typical dimension tolerance is ±0.2mm, better precision is available upon request.
(4). Typical FWHM (transmitted wavelength range, as defined by the Full Width Half Maximum of transmission
      curve) from 10nm to 80nm, broadband from 1nm to 100nm are available upon request.
(5). Typical wavelength tolerance is ±2nm when FWHM is 10nm, better precision is available upon request
(6). Typical surface quality is 80/50, better precision such as 60/40, 40/20 is available upon request.
(7). Wavelength is various due to different applications, they are UV (200nm-399 nm), VIS (400nm-700nm),
      IR (750nm-2500nm), Please tell us your special use wavelength.
