Substrate & Coating Advantages

UV-Grade Fused Silica Substrate :

• Exceptional thermal stability and ultra-low thermal expansion for consistent performance across temperature variations

• High purity (>99.9%) minimizes absorption and scatter – critical for high-power laser applications

• Excellent transmission from UV through near-IR

• High resistance to laser-induced damage

• Superior mechanical strength and chemical durability

Broadband AR Coating (720-780 nm) :

• Multi-layer dielectric coating engineered for maximum transmission in the NIR band

• <0.2% average reflectivity per surface ensures minimal optical loss

• Optimized for 0° angle of incidence, supporting common laser sources including Ti:sapphire and diode lasers

• Hard, durable coating resistant to cleaning and environmental exposure

• Vacuum-deposited for superior uniformity and adhesion

Military-Grade Surface Quality :
The 10-5 scratch-dig specification per MIL-PRF-13830B represents the highest standard of surface quality, with:

• Scratch width: 10 (extremely fine, barely visible under magnification)

• Dig diameter: 5 (tiny imperfections, 0.05mm max)

• Zero visible defects under inspection – critical for space and defense optics where even minor imperfections can compromise performance

Transmitted Wavefront Error (TWE) :
< λ/10 peak-to-valley at 633 nm ensures:

• Near-diffraction-limited performance

• Minimal wavefront distortion in transmitted beams

• Preservation of beam quality in high-precision systems

Provenance & Rarity

Crafted as a single-unit prototype for a leading U.S. defense research laboratory, a forefront institution in national security technologies, this optic was tailored for a defense-related space project, likely involving:

• Laser-based remote sensing

• Beam propagation in vacuum

• Optical payloads for satellites

Its custom design, military-grade specifications, and single-unit production make it a rare find in the surplus market – not a standard catalog item, but a precision component fabricated for a specific mission-critical application.
