Optolong LRGB 2 Inch Filters

Introducing the Optolong LRGB 2 Inch Filter Set Kit

The Optolong LRGB 2 Inch Filter Set Kit is a vital accessory for any astrophotographer or astronomer seeking to capture stunning, high-contrast images of the night sky. This set of four filters—Luminance (L), Red (R), Green (G), and Blue (B)—is meticulously designed to separate the light spectrum into its primary components, allowing for detailed and accurate color representation in your astrophotography. With these filters, you can achieve exceptional image quality, making it easier to photograph deep-sky objects and planetary details.

Features of the Optolong LRGB 2 Inch Filters

The Optolong LRGB 2 Inch Filter Set Kit is packed with advanced features that cater to the needs of serious astronomers and astrophotographers:

• High Transmission Rates: Each filter in the set boasts a 95% transmission rate at the passband, ensuring high efficiency and natural color imaging.
• Effective Light Pollution Blocking: The filters are designed to block out the primary Sodium (Na) light pollution line at 589nm, improving color balance and separation.
• Infrared Blocking: The filters also block infrared wavelengths (700-1100nm), eliminating the need for a separate IR cut-off filter.
• Optical Precision: Both surfaces of the filters are fine optically polished to 1/4 wavelength or better, with parallelism within 30 seconds of arc.
• High-Quality Glass: Made from 2mm thick Schott B270 optical glass substrate, the filters offer excellent durability and performance.
• Advanced Coating Technology: Multi-layer anti-reflection coatings and non-cementing optical substrate coatings ensure high transmission and blocking of unwanted wavelengths. The electron-beam gun evaporation with ion-assisted deposition technology enhances durability and resistance to scratching.
• Standardized Threads: The filters feature a 2-inch astronomy filter with standard M48x0.75 male filter thread.
• Ultra-Thin Design: The ultra-thin filter cell minimizes vignetting, providing a clear optical aperture of 45mm.
• Durable Construction: Precision CNC-machined metal filter cells with a sand-blasted black anodized finish, anti-reflection treatment, and laser engraving ensure long-lasting use.
• Protective Storage Case: Each filter comes with a high-quality protective plastic storage case to keep them safe when not in use.
