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.
Thermal variation is the largest source of error in all areas of high precison 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 your optics manufacturing operation.
Even with a temperature variation of +/- 0.1 ºC significant errors will still occur. However, by maintaining the temperature variation to +/- 0.003 ºC, a typical high precison instrument will improve its accuracy by approximately ten times.
Extremely accurate temperature control at the Critical Point increases accuracy and profitablity.
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.
