This series was developed for mass-production market needs. Production-proven equipment offers high productivity and the lowest ownership cost for cost-optimized volume production of optical components. It can produce AR, UV/IR cutoff filters, AF, hard coatings, decorative coatings, ITO coatings, bandpass filters and HR coatings. Equipped with an electron gun, pocket-type, kidney-shaped or annular crucibles and an impedance-type evaporation source. Optical or quartz-crystal thickness monitoring enables automatic control of deposition rate and coating processes. Optional RF/Kaufman-type/Hall-type ion sources. AR coatings (substrate glass transmittance >91.5%): in the 420-680nm band, single-sided average transmittance >95% and reflectance less than 0.5% (average); double-sided average transmittance >98% and reflectance less than 0.5% (average). AS/AF coating test standards: initial contact angle 115±5°; steel-wool abrasion test using 0000# steel wool over 10*10mm, 40 strokes/min, load 1Kg: contact angle greater than 100° after 5000 reciprocating rubbing cycles; eraser test using a 6mm-diameter eraser, 25 strokes/min, load 1Kg: contact angle greater than 100° after 2500 reciprocating rubbing cycles. Note: glass test samples must be precision-polished glass specifically for touchscreen cover plates, with a clean, smooth surface.

Abbe number: 72.24 Birefringence [Visible light orthogonal to the optical axis]: 0.008 Clear Aperture Dimension: ≥90%

Sapphire windows retain high strength at elevated temperatures, with good thermal properties and excellent transparency. They resist common acids and alkalis at temperatures up to 1000°C and hydrogen fluoride below 300°C. These properties support use in harsh environments requiring optical transmission from vacuum ultraviolet to near infrared.

Colored glass modifies the spectral characteristics of optical radiation for scientific experiments and industrial applications requiring such changes. Colored-glass filters can be combined to modify the passband or increase attenuation.

Available materials [Series supply]: N-BK7, UV fused silica or other optical glass Dimensional Tolerance [Standards]: +0/-0.2 Dimensional Tolerance [Processing Upper Limit]: +0/-0.05

Right-angle prisms commonly alter optical paths or redirect beams by 90°. Designed with a 90° angle, they produce inverted or reversed left-handed images depending on orientation. Using two together is ideal for image or beam displacement. Also called mirror-image reflecting prisms.
