Responding to the increasing competition
in optics manufacturing.
The fabrication of optics relies on the determinism of computer controlled manufacturing and the elimination of errors such as thermal dimensional variations.
It has long been known that thermal variation is the largest source of error in all areas of high precision manufacturing. Reducing thermal variation not only improves accuracy, but the reduction in error provides greater latitude in managing an error budget.
Increase the precision of optics manufacturing.
Even with a temperature variation of 0.1 ºC significant errors will occur. However, by maintaining the temperature variation to ± 0.01 ºC, a typical precision instrument will improve its accuracy by more than ten times.
Precision temperature control at the Critical Point increases accuracy and profitability.
This graph shows displacement of a diamond turning spindle at room temperature over 2.5 hrs. There is a 1.25 μm (p-v) axial displacement resulting from a 1.0 ºC (p-v) variation in ambient temperature.
Even though an ambient fluctuation of 1.0 ºC is typical, a spindle displacement of 1.2 μm is unacceptable for most diamond turning applications.
