Astrophotography

Filters and filter sets

According to the characteristics of the emission line of the celestial target and the emission line of light pollution (see Table 1), the astronomical filter can effectively reduce the influence of harmful light, suppress the background light of the target, improve the contrast and detail of the astronomical photograph, save a lot of time in the shooting process, and obtain better shooting results.

XIMEI Optical Filters include F-Dual-Band Pass System, S-Single Narrowband Series, W-Broadband Series, M-Multi-Band Pass Series, Sloan Metering Series, etc. All filters are made with the finest monolithic substrate glass using a durable hard coat using the PVD IAD process. The products are double-coated, with the front surface coated with the main film and the rear surface coated with an anti-reflection coating to prevent ghosting and maximize transmittance. The company controls halo through rigorous production processes and quality inspections, resulting in clearer, sharper images and higher contrast. 

In addition to the built-in filter thickness of 1mm, the thickness of the optical filter products of XIMEI Optical Filter is 2mm.

* F-dual band pass system includes D-OH01, D-OH02, FD-OH01;

* S-Single Narrowband series includes S-HA01, S-HA02, S-Hb01, S-Hb02, S-SII01, S-SII02, S-OIII01, S-OIII02;
