Each filter uses a high-quality optical glass substrate with a multi-layer composite coating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWho It's For.\u003c\/strong\u003e The set suits imagers running larger-sensor monochrome cameras and 2\" filter systems who want full-color results with the resolution and sensitivity advantages of mono capture, whether photographing galaxies, reflection nebulae, or star fields.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features \u0026amp; Design.\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete LRGB channel coverage:\u003c\/strong\u003e Luminance, Red, Green, and Blue filters combine into balanced true-color images.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh throughput:\u003c\/strong\u003e approximately 95% transmittance in-band keeps exposures efficient.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOff-band blocking:\u003c\/strong\u003e OD3 blocking (less than 0.1% off-band transmission) with NIR cutoff across 700–1100nm holds channel separation clean.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2\" clear aperture:\u003c\/strong\u003e the larger format supports bigger sensors and fast focal ratios with even illumination.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision surfaces:\u003c\/strong\u003e 1\/4 lambda surface accuracy on a 2.0 ±0.03 mm substrate supports sharp, consistent focus across channels.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOptical\/Mechanical Design.\u003c\/strong\u003e Each filter uses a multi-layer composite coating on a 2.0 ±0.03 mm high-quality optical glass substrate polished to 1\/4 lambda on both surfaces.
