Narrow band filter ≤ 400nm can be customized,
For example, 214nm, 220nm, 250nm, 254nm, 257nm, 260nm, 265nm, 272nm, 273nm, 275nm, 280nm, 285nm,
300nm、310nm、315nm、316nm、320nm、325nm、340nm、345nm、
350nm, 361nm, 365nm, 370nm, 380nm, 400nm and other narrowband filters.

Narrow-band filters with a value greater than or equal to 1000nm can be customized,
For example, 1040nm, 1055nm, 1064nm, 1070nm, 1075nm,
1125nm、1250nm、1450nm、1550nm、1653nm、
Narrowband filters such as 1680nm, 2050nm, 2230nm, 2340nm, etc.

Product Size:2mm-80mm (customizable)

Cut-off wavelength:200nm-400nm (customizable)

Cut-off depth:>OD3-OD6
(The higher the OD value of the cut-off rate, the narrower the pass bandwidth and the lower the peak transmittance.)

Product material:Optical grade glass
(Such as K9, BK7, B270, D263T, JGS1, color glass, float glass, etc.)

Surface finish:National Standard Level 3, US military standard 60-40.

Packaging: vacuum dust-free packaging for optical filters.

Advantages:

◆ adopting the technology of all-medium hard film coating and the principle of Medium interference, on the basis of highlighting the characteristics of narrow band filter, the optical performance has nothing to do with the thickness of the substrate,
It is convenient to be built into the imaging system of the instrument, so that the optical performance can be improved and effectively applied;
◆ special optical base materials are adopted to solve the problems of fog-prone and unstable optical properties of absorbing synthetic glass in the traditional sense.
