Optical Bandpass Filters
Optical Bandpass Filters
*Bandpass filter plate are divided into short-pass and long-pass filters according to whether they transmit below or above the transition wavelength. The transition wavelength or cut-on/off wavelength is the wavelength at which the transmission is 50% of its peak value.
*Specifications:
Material: N-BK7 ;Fused silica
Dimension Tolerance: +0.0, -0.1mm
Thickness Tolerance: ±0.1mm
Surface quality: 60/40
Clear Aperture: >85%
Parallelism: λ /4 per 25mm@633nm
Bevel: ±3
Coating: One surface(S1) :HR & HT
The other surface(S2):Upon requirement
