Altair 90mm Aperture TRIBAND D-ERF Solar Energy Rejection Filter - H-Alpha CaK CaH (95mm Glass)

Altair 90mm Aperture TRIBAND D-ERF Solar Energy Rejection Filter - H-Alpha CaK CaH (95mm Glass)

Reduces approx. 98% of heat reaching the optics to keep Etalon from drifting off-band and protects your expensive equipment.
Spectrographic Transmission test report included showing the performance of each individual filter.
32-36nm FHWM Bandpass at H-alpha wavelength of 656.28 nm Transmission ~ 95-98% (Tolerance is about 3%).
32-36nm FHWM Bandpass with CWL at 395nm covering Calcium H-Line and Calcium K-Line wavelengths. Transmission - 85-90% (Tolerance is about 3%).
Visible light blocking (area of maximum solar radiation and heat generation): Average OD4 ~0.001%T @400-700nm.
UVIR average blocking OD5 ~0.001%T between 200-1100nm
Extra Deep IR Blocking up to 1700nm Average OD2 (1%) (lowest solar radiation).
Quartz Element Diameter 95mm, Thickness 8mm, Weight 125g
Multilayer coatings with SiO2 protective overcoat for a long life and easy cleaning.
ERF Holder cell included with soft tip threaded knobs. Tough and very light, easy to disassemble for cleaning the filter with optical wipes. Cell does not put any tension on the optics. For this reason the glass element is able to move slightly within the cell by about 0.5mm.
