Core offering

Optolong Optics Co. designs, develops, and manufactures precision-coated astronomical optical filters, including narrowband (H-Alpha, OIII, SII, H-Beta), dual-band, quad-band, multi-bandpass broadband, LRGB, planetary, and photometric filters used by amateur and professional astrophotographers and scientific researchers. Products are built with proprietary ion-assisted deposition coating on non-cementing optical substrates, offered in 1.25", 2", M77/M82, unmounted, and camera-clip formats (Canon EOS, Nikon Z, Sony FF), and sold globally through authorized dealers and direct website sales.

Product overview

Optolong Optics Co. is an integrated enterprise specializing in R&D and manufacturing of astronomical optical filters. The company offers a comprehensive portfolio of astrophotography filters organized into five main product categories: Wide-Field Astro Filters (L-Pro, Clear Sky), Deep-Sky Imaging Filters (L-eXtreme, L-Ultimate, L-eNhance, SHO narrowband kits, H-Alpha, OIII, SII, H-Beta), Planetary Filters (LRGB sets, UV/IR Cut, IR Pass, Venus-U), Camera Clips (Canon EOS-C/FF, Nikon NK-FF, Sony Sony-FF), and Scientific Research Filters (Photometric UBVRIc). Core products include multi-bandpass light pollution suppression filters like L-Pro, dual-band narrowband filters like L-eXtreme and L-eNhance, and ultra-narrowband filters like L-Ultimate. Products are available in various formats including 1.25 inch, 2 inch, clip-in designs for specific camera systems, and unmounted options for filter wheels. The company also offers combination sets like L2 Dual-Combo (L-eXtreme + L-Synergy) and SHO narrowband filter kits for Hubble palette imaging.
