Optolong LRGB Filters

Introducing the Optolong 2" LRGB Filters

The Optolong 2" LRGB Imaging Filter Set is a must-have for any serious astronomer or astrophotographer looking to capture the true colors and intricate details of the cosmos. Designed with the highest standards of quality and performance, this filter set separates the light spectrum into its fundamental components: Luminance (L), Red (R), Green (G), and Blue (B). This separation allows for maximum contrast and color accuracy in your astrophotography, ensuring that you capture the universe with unparalleled clarity and precision.

Features of the Optolong 2" LRGB Filters

The Optolong 2" LRGB Filter Set is packed with features that make it an indispensable tool for astrophotography:

• High Transmission Rates: The filters provide 95% transmission at the passband, ensuring bright and clear images.
• Effective Light Pollution Blocking: The gap between the green and red filters blocks the primary Sodium (Na) light pollution line at 589nm, enhancing color balance and separation.
• Infrared Blocking: These filters also block infrared wavelengths (700-1100nm), eliminating the need for a separate IR cut-off filter.
• Precision Polishing: Both surfaces of the filters are fine-optically polished to 1/4 wavelength or better, with parallelism within 30 seconds of arc, ensuring superior image quality.
• High-Quality Materials: Made from 2mm thick Schott B270 optical glass substrate, the filters offer excellent durability and reliability.
• Advanced Coating Technology: Features multi-layer anti-reflection coatings and non-cementing optical substrate coatings, applied via electron-beam gun evaporation with ion-assisted deposition, for enhanced durability and scratch resistance.
• Durable Filter Cells: The precision CNC-machined metal filter cells are lightweight and strong, with a clear aperture of 45mm, and feature a sand-blasted black anodized finish and anti-reflection treatment.
• Laser Engraving: Ensures that all markings remain legible over time and do not fade.
• Ultra-Thin Design: The ultra-thin filter cells minimize vignetting, providing a clear optical aperture.

Applications of the Optolong 2" LRGB Filters

This filter set is ideal for a variety of astronomical applications, particularly in environments with moderate to high light pollution:

• Deep-Sky Imaging: Perfect for capturing detailed images of nebulae, galaxies, and star clusters with accurate color representation.
• Planetary Imaging: Enhances the details and colors of planets in our solar system.
• Monochrome CCD Imaging: Works exceptionally well with delayered monochrome CCD cameras, providing the raw material needed for image processing in the sRGB color space.
