Specifications
-
Substrate Material: UV Fused Silica (JGS1 — low autofluorescence, high damage threshold) / N-BK7 (K9 — VIS-grade, cost-effective)
-
Diameter: 16.0 mm (+0.0 / −0.05 mm)
-
Thickness: 2.0 mm (±0.1 mm); 1.5 / 3.0 mm on request
-
Optical Function (select one or combo):— Protective Flat Window — Planar-plano, BBAR @ 755 nm (or 532/1064 nm if multi-band)— Honeycomb / Microlens Array (MLA) — Hexagonal micro-cells or lenslets on entrance side to homogenize intensity; exit side flat or slightly convex— Diffuser / Top-Hat Homogenizer — Engineered surface roughness / microlens pattern for uniform far-field— Combined: Honeycomb on front + AR flat on back (most common for picosecond aesthetic)
