The IRD advantage
Custom
components.
Controlled quality.
IRD Glass is built for OEM teams that need more than a commodity glass supplier.
IRD does not design your optic. It reviews your design for manufacturability, tells you what the print will really cost to hold, and then builds it the same way every run.
Hold the tolerances that decide the system
Polishing to 30 arc sec parallelism typical and better than 5 arc sec at best, flatness to better than 1/20 wave, roughness to Ra < 5 Å. Machining to ±.0001″.
One roof, and one cell that owns the part
Machining, polishing, coating, assembly, and inspection are coordinated in-house, and a dedicated cell of people and equipment carries your component from raw-material order through final inspection.
Prove it across a production run
98%+ on-time delivery for the past decade, on programs that have run twenty years and longer for the same customers.

How IRD supports technical OEM programs
Custom fabrication
Cut, shape, grind, drill, polish, machine, coat, and assemble glass and ceramic components to project specifications.
In-house machining
CNC processing and specialized fabrication equipment help IRD customize precision materials with control and speed.
Optical coatings
Quick-turn basic coatings in-house on two e-beam chambers and a DC magnetron sputtering chamber — AR, high-reflector, HLDT, beamsplitter, notch, BBAR, and metallization across UV, visible, and IR.
Program continuity
The same cell that made the first article makes the thousandth, tied to the same print revision. No requalification because a job moved benches.
Inspection discipline
Zygo GPI, NewView, and 6″ Verifier interferometers, a Wyko 6000 PS with computer-generated holographic cylinder nulls, Nikon 6D interferometry and autocollimation, and OGP CNC vision — inspecting in process, not only at the end.
PRECISION TEAMS
CUSTOM COMPONENTS
Twenty years and millions of precision components into a single Honeywell sensor program.

Proof in the process ↓
ISO 9001:2015 and ITAR registered
The certificate covers both Minnesota facilities. The quality system is certified — an individual part is not, which is why every print gets its own inspection plan. ITAR-controlled work is manufactured and stored domestically.
QUALITY SYSTEM
98%+ on-time, past decade
IRD's reported delivery performance across long-running programs. On one high-power laser mirror, process development and a dedicated production cell cut cycle time from over eight hours per piece to under one in volume.
DELIVERY RECORD
Arc-second precision
Polishing to better than 5 arc sec parallelism, better than 1/20 wave flatness, and Ra < 5 Å. Machining to ±.0001″ and up to 30″ × 16″ × 16″. Every surface quoted to what the system needs, not to a blanket grade.
PRECISION OPTICS
Honeywell, Collins Aerospace, TRUMPF, 3M, Alcon, TDK
IRD serves laser, medical, aerospace, defense, sensor, and industrial OEMs — including customers whose programs have run with IRD for two decades and more.
CUSTOMERS SERVED
In-house customization
Six HAAS CNC mills, OMAX waterjet, dicing and slicing saws, cylindrical and pitch polishing to 48″, two e-beam coating chambers, and DC magnetron sputtering — plus proprietary fixturing and tooling built when an application needs a new approach.
CAPABILITIES
Built to print, reviewed for free
IRD does not design optical components. It works with your designers on manufacturability, provides a no-cost DFM review on a new design, and then quotes prototype and production volumes separately.
CUSTOM MANUFACTURING
How we manufacture.
We start with the print, performance requirements, material, tolerance stack, and production goals. Then IRD aligns the right fabrication route, validates the process, inspects the work, and supports the program from first article through repeat production.
A clearer product
starts with better components.
IRD turns difficult component requirements into parts that can actually be manufactured — repeatably, at volume, on a schedule a program can plan around.
It is built for OEMs that need tolerances a catalog cannot hold, materials most shops will not quote seriously, and a supplier who says what a print will really cost before the first article rather than after the third production run.
Across laser, medical, aerospace, defense, sensor, and industrial programs, IRD pairs four decades of manufacturing depth with the inspection discipline high-consequence components require.
