Products classified under HTS 9005.80.40.20
Infrared Astronomy Telescope
A specialized optical telescope designed for infrared light observation of celestial bodies, featuring cooled detectors and precise optics for deep-space imaging. It falls under HTS 9005.80.40.20 as an optical telescope specifically for use with infrared light, used in astronomical research. This classification distinguishes it from visible light telescopes or radio-astronomy instruments.
Near-Infrared Reflecting Telescope
A Newtonian reflecting telescope with IR-optimized parabolic mirrors and low-OH glass for near-infrared astrophysics research. HTS 9005.80.40.20 applies due to its specific design for infrared light in astronomical applications, distinct from general reflectors.
Cryogenically Cooled IR Telescope Assembly
Complete telescope system with cryogenic cooling for infrared detectors, enabling low-background thermal imaging of astronomical sources. HTS 9005.80.40.20 classification for infrared optical telescopes including mountings and accessories.
Long-Wave Infrared Observatory Telescope
Large-aperture telescope for 8-14μm long-wave infrared astronomy, featuring specialized cold-stop baffling. Specifically classified under HTS 9005.80.40.20 for infrared optical telescopes used in observatories.
Compact Infrared Finder Telescope
Small auxiliary telescope for infrared guiding and finding of astronomical targets, mounted on primary telescopes. Falls under HTS 9005.80.40.20 as an optical telescope accessory specifically for infrared use.
IR-Enhanced Schmidt-Cassegrain Telescope
A catadioptric Schmidt-Cassegrain optical design telescope optimized for infrared wavelengths, with special coatings and filters for near-IR stellar observation. Classified under HTS 9005.80.40.20 for its infrared-specific use in astronomical telescopes. Excludes radio-astronomy instruments per chapter exclusions.
Mid-Infrared Adaptive Optics Telescope
Advanced telescope with deformable mirrors and wavefront sensors for mid-infrared (3-5μm) atmospheric correction in astronomy. Falls under HTS 9005.80.40.20 as an infrared-specific optical telescope with mountings for astronomical use.
Infrared Spectroscopic Telescope
Optical telescope integrated with IR diffraction gratings for simultaneous imaging and spectroscopy of astronomical objects. HTS 9005.80.40.20 covers this as an infrared optical telescope despite spectroscopic capability.
