Lightweight polymer optics for tactical platforms — without the marketing fluff.
Scopes, sights, weapon-mounted devices, illuminators, UAS sensor optics, and helmet-mounted displays live or die on weight, ruggedization, and environmental envelope. We design and manufacture polymer optics where they earn their place, and we tell you plainly where glass is still the right call.
Why a defense program reaches for polymer optics in the first place.
- Weight
- Soldier-borne and weapon-mounted systems are weight-budgeted line item by line item. Polymer elements remove glass mass at the optic without removing performance from the imaging path.
- Breakage envelope
- Drop, impact, and recoil that fragment glass leave polymer optics intact. Survivability under shock and vibration is a design parameter we model, not a marketing claim.
- Complex geometry
- Freeform reflectors, conformal windows, and integrated baffles mold to net shape with internal datums — geometry that grinding and polishing cannot reach economically.
- Cost at scale
- Once the cavity is qualified, lot economics fall well below the equivalent glass element. Programs that move to fielded volume benefit per part and per platform.
The places we will tell you to use glass instead.
- High-power laser exposure
- Polymer optics do not belong in laser pump cavities or high-CW illuminator paths where absorption and bulk damage thresholds matter. Use glass; we will tell you so.
- Extreme environmental envelopes
- Sustained operating temperatures above the resin's glass-transition limit, or coatings forced past their thermal stability window, will degrade contrast and form. If the spec lives in that region, polymer is not the answer.
- Diamond-machined optical-grade surface metrology
- When the surface-quality call is below what a diamond-turned polymer master plus replication can deliver — sub-nanometer figure on the optical-grade glass tier — that is glass territory, not ours.
Where polymer optics show up across tactical and defense programs.
- Riflescopes
- Lightweight objective and erector optics for variable and fixed-power scopes; recoil-survivable mounting datums; coatings stable across the operating thermal envelope of the platform.
- Red-dot reticles
- Molded freeform reflectors and projector optics with parallax and reticle-position stability through drop, shock, and recoil. Polymer where ruggedization beats glass; glass where the spec demands it.
- Illuminator optics
- TIR collimators and projection optics for white-light, IR, and laser illuminators that have to take a beating outside the laser cavity itself. Polymer is on the projection side; we will say so when it is not.
- UAS sensor optics
- EO/IR sensor windows and lens stacks for tactical UAS payloads — weight, vibration, and thermal envelopes met without putting glass mass on a gimbal that does not want it.
- Helmet-mounted displays
- Combiner-side and projector-side freeforms for HMDs where weight, eye-relief, and lifetime durability drive the polymer-versus-glass call. Optical clarity verified on the production cavity, not the prototype.
US manufacturing, export-control awareness, and traceable lot documentation.
Sandia Optical manufactures in Albuquerque, New Mexico. Programs that require domestic manufacturing of optical components for defense end-use are supported end to end — from prescription review through SOP — on US soil.
We are ITAR-registered with the U.S. Department of State (DDTC) and support USML-controlled items under documented export-control procedures. Export-controlled drawings, technical data, and lot documentation move under the handling rules each program's classification calls for; we do not accept controlled data outside those procedures.
Lot traceability is standard on every defense program: cavity, resin lot, coating run, and metrology record travel with the parts. Programs that require AS9100D coverage should plan the customer-side flowdown accordingly; Sandia operates to ISO 9001:2015 with the defense-program documentation rigor listed above.
