◆ Application
Airborne/Shipborne Multispectral Observation System: Designed for infrared night vision devices, laser sights, etc., it maintains stability in low-temperature observation windows or in high-salt spray marine environments.
Semiconductor manufacturing and inspection equipment: As substrate for epitaxy (such as in SOS technology) or as windows for lithography machines, they can withstand strong acid/strong alkali cleaning environments, and the crystal orientation accuracy is strictly controlled.
Deep-sea probe observation window: Can withstand high pressure (>100 MPa) and salt corrosion environment, replacing traditional quartz glass to extend service life.
Dimensional requirements: The outer diameter and thickness shall be determined based on the spatial layout of the optical system and the beam size.
Mounting configuration: All circular lenses from Mloptic can be mounted on standard lens sleeves, fixed lens mounts, and various coaxial mounting plates.
Coating requirements: The coating quality must comply with general specifications for optical coatings. Scratches or contamination on the coating should be avoided as they may affect the anti-reflection performance.
Cleaning taboos: Avoid cleaning with corrosive solvents such as strong acids and alkalis, as they may damage the anti-reflection coating and glass substrate. It is recommended to use optical-specific cleaning agents (e.g., isopropanol, diethyl ether) and gently wipe with soft lint-free cloths or lens paper to prevent surface scratches.
Transportation and storage: Optical surfaces must be strictly protected during transportation. When packaging, direct contact between protective films and optical surfaces is prohibited to prevent contamination by foreign substances or scratches.
