BLASI – Filter cover IR D80mm, black

The BLASI – Filter cover IR D80mm, black mounts directly over ELS300 transmitter/receiver lenses and ESPROS/GO-V IR camera apertures, precisely passing 830-870nm near-infrared wavelengths required for time-of-flight distance measurement and modulated light barrier detection while blocking >99.9% visible light from 400-700nm that causes false triggering in shopping mall fluorescent lighting and direct sunlight penetration through glass drum walls. The optical density OD4+ specification maintains infrared transmission >90% across operational temperature range -20°C to +70°C typical for Dubai commercial entrances.

Manufactured from durable polycarbonate with hardened scratch-resistant coating, the 2mm thick filter withstands cleaning chemical exposure, mechanical impact from cleaning equipment, and UV degradation during years of continuous service while maintaining molecular-level adhesion preventing delamination common in inferior optical components. Black anodized aluminum bezel provides light-tight seal against drum frame mounting surfaces while three-point snap-fit retention system enables tool-free field replacement during routine sensor maintenance without system downtime.

Factory pre-aligned concentric design ensures pixel-perfect infrared path registration when replacing contaminated filters while matte black interior surfaces eliminate stray light reflections that degrade ESPROS 3D depth map accuracy critical for advanced anti-entrapment algorithms. Technicians value color-coded black designation distinguishing IR filters from clear protective BLASI – Filter covers, sequential batch numbering for inventory tracking across multi-door facilities, and exact 80.2mm outer diameter matching factory drum cutouts across all FlipFlow generations ensuring uninterrupted safety system performance worldwide.
