Bandpass Filter
Band-pass filters are optical components that can make certain wavelengths of light through and let the light of other bands reflect (or attenuation) .
Their working area is ultraviolet light, visible/near infrared light, far infrared wavelengths and they are can be decided according your application.
Product application:
Biochemical, medical, image recognition, detection sensor, laser system, etc .
Standard wavelength: (UV, visible, near infrared)

The bandpass filters of other wavelength, material and size can be customized according to the customers’ requirements .
Bandpass Filters include two types: Narrow Band Filters and Broad Band Filter.
a.Narrow Band Filters ,the characteristic is the half bandwidth Δλ is general controled in less than 20 nm.
Product application:
Biochemical, medical, image recognition, detection sensor etc
Product material:
K9 glass, quartz glass, etc
Size:
φ10, φ12.7, φ15, φ25.4 mm. Any other size can be customized, maximum size 55 × 55 mm
b.Broad Band Filter It is used in isolating a wider band monochromatic light from compound light. The half bandwidth Δλ ,Δλ≥0.01λ0, λ0 is the center wavelength of the filter′s transmitting light curve
