OPTOLONG UHC Filter Light Pollution Filters as astronomical camera filter

الوصف

Brief Introcuction of UHC Astronomy Filters:
 

UHC is Shroten written from Ultra High Contrast, UHC is also a broadband filter with an obvious effect on blocking city harmful lights. UHC filter blocks lights selectively, especially the mercury and sodium light from manmade lamps and the skyglow in nature. UHC filter lets the light from nebula highly transmit, it has a high transmittance at the region of OIII(**6nm & **0nm), Hβ(**6nm), NII(**4nm &**8nm), Ha(**6nm)and SII(**2nm). Our UHC with higheffectively improved the contrast of the nebula ,ensuring wonderful nebula details.

 

OPTOLONG UHC filter astounding high light transmission brings better views of deepskyobject even to small telescopes. The high transmission of our optical glass filters means that enough light is available to allow successful visual observations with telescopes beginning at 2" (*0mm) aperture. Our filters are optimized for use with telescope focal length f / ratios of f/4 to f/*5. Another major advantage of our UCH filter is the high optical quality of the filter glass. When using OPTOLONG UHC filter, you will quickly notice the same needle-sharp stars which you are familiar with from your astronomical instrument without any filter.

Advantage of OPTOLONG Astronomy Filters:

*5 years of experience in optical filters

Ion assisted deposition technique ( IAD) using

The high film layer density, high film layer firmness, high performance and stability.

A wide range of cut-off，High cut-off depth，High transmittance.

Effectively prevent stray light interference.

All filters are RoHS requirements.

OEM and ODM are welcomed!
