Precision glass and optical component manufacturing.

Send a drawing, a specification, or the manufacturing problem. IRD's applications team will review the material, geometry, tolerances, inspection requirements, quantity, and schedule together.
Prefer to talk it through first? Call 320.693.7217 and ask for an applications engineer.Tell us why you are getting in touch and the team routes it from there. For a quote, include the geometry, tolerances, application, inspection requirements, and any open questions. A complete print is useful but is not required for the first conversation.
By submitting, you authorize IRD to use the information to evaluate and respond to this project inquiry. Do not include passwords, unrelated personal information, ITAR-controlled data, or other export-controlled technical data.There is no responsible shortcut from upload to price. IRD reviews the manufacturing route and the open questions first.

The team checks the print, material, critical features, inspection requirements, quantities, and requested timing.
If a tolerance, material callout, datum, coating requirement, or application constraint needs clarification, IRD asks before assumptions enter the quote.
Machining, grinding, lapping, polishing, coating support, cleaning, inspection, and repeat-production needs are considered as one process.
You receive the questions or the commercial response through the contact details in the submission. Straightforward geometry moves quickly; a new material, coating, or inspection method takes longer because someone is checking it.
Some components begin with an operating condition or a failed process, not a finished drawing. Call the main line when a conversation is the better starting point.
