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!
