The LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colors. The LRGB filter set divides the spectrum into its components red, green, blue and luminance. OIII emission overlaps on blue and green filters with maximum transmission to allow high efficiency and natural color imaging. Gap between green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves color balance and separation.

Fine-optically polishing for double-sides—— Ensure accurate ?/4 wavefront and <30 seconds parallalism over the both surfaces

Ultrasonic wave cleaning substrate with purified water—— Cleanup by 13 purified water tank to remove inpurities and dust effectively

Iro source assisted coating—— For durability and resistance to scratching, as well as stability on CWL (central wavelength) no deviation affected by temperature change.
