Optimax provides rapid delivery services for prototype optics ranging in size from 10-100mm. While 10 week delivery for prototype optics is typical in the industry, Optimax offers 6 week standard delivery with the option for expedited deliveries as fast as 1 week. The Manufacturing Tolerance Chart provides tolerance guidelines for prototype optics with optical surfaces of f/1 or slower and made from Optimax Preferred Glasses. Consult this chart to determine appropriate tolerances and click on any attribute to show a detailed definition.
Careful consideration should be given to the manufacturing tolerances. As a general rule, price increases around 50% going from Commercial to Precision and another 50% from Precision to High Precision. For more insights regarding tolerancing versus cost, please see “The cost of tolerancing.”
