OPTOLONG LRGB Set (36mm, without housing)

These LRGB filters produce by very steep filter skirts for excellent color differentiation.

Use:
For shooting devices without Bayer mask (monochrome CCD or Planetencam). The filters are suitable for color photography, both in the field Deep Sky as well as planetary images.

Technical specifications

• Supporting glass of Schott
• Surface Quality 60/40 (corresponding to the EE kindness by American military standard MIL-O-13830)
• Fine optically polished, 1/4 wavefront
• 95% peak transmittance in the passband
• IR Blocking 700-1100nm in the stop band / off band

Coating properties:

High Homogeneous multilayer anti-reflection coating
The allowances are not cemented to the optical carrier, but applied Deposition (IBAD) method by electron beam evaporation and subsequent ion beam assisted.
This special process allows a high durability and scratch resistance, and high stability of the center wavelength (CWL) and prevents a temperature drift.
High transmission in the passband, high optical density in the stop band.

Filter version:

• Ultrathin filter mount for maximum passage: 26mm at the 1.25 "filters, 45mm at the 2" filters 
• Precise CNC manufacturing 
• Sandblasted Black anodized 
• blackened to reflections 
• Laser engraving - no fading of the label
