ZWO 2"LRGB fiter set (SKU: ZWO LRGB2)

ZWO LRGB 2 is a remarkable set of four professional astrophotographic filters designed to work seamlessly with monochrome cameras. These filters boast exceptional performance, with each one surpassing 90% efficiency within its maximum transmission band. The combination of high-quality Schott glass substrates and a comprehensive multilayer coating guarantees incredibly vivid and contrasting images.

One notable feature of the ZWO LRGB 2 filters is the deliberate separation of the maximum transmittance for the G (green) and R (red) filters. This strategic selection effectively eliminates signal interference originating from the spectral lines of sodium and mercury lamps, which are notorious culprits of light pollution in astrophotography.

Let's delve into the key features of the ZWO LRGB 2 filters:

High-Quality Schott Optical Glass Substrate:

The filters are constructed using premium Schott optical glass, ensuring exceptional durability and optical performance.

Effective Elimination of Spectral Lines:

The G and R filters are designed to eliminate spectral lines emitted by sodium and mercury lamps, which significantly reduces light pollution in astrophotography.

Scratch-Resistant Multilayer Anti-Reflection Coating:

A robust multilayer anti-reflection coating is applied to the surface of each filter, safeguarding them against scratches while enhancing light transmission.
