903nm narrow-band filter
Narrowband 903nm laser range finder filter (narrow band pass filter) is a kind of bandwidth is very narrow, short wave and long wave has obvious cutoff, can make specific wavelengths of light by light reflection and let other band (or decay) optical elements. With the work area pass filter can be ultraviolet, visible, near infrared, far infrared, in accordance with the scope of application depending on your. Half bandwidth (FWHM) of less than 25nm, the center wavelength of positive and negative 1.0nm, peak transmittance greater than 85%. A thickness of less than 1.2mm. is suitable for measuring instrument, laser range finder, a variety of test system, night vision and other products.
