Earlier this year SCHOTT Advanced Optics has introduced its well known ZERODUR® in two new versions of the expansion class 0 with much tighter CTE tolerances: ZERODUR® SPECIAL with a CTE of (0 °C, 50 ...

Zerodur is a glass ceramic that's one of the most expensive materials around, so getting it right the first and every time it's cut is critical. Through the use of ultrasonic machining on various ...

Zerodur optical flats are also available in lambda/10 and lambda/20 types from stock. We can also supply lambda/4, lambda/8 and lamda/16 optical flats on short lead times. All optical flats are tested ...

ZERODUR® is a proven material that has been selected for four of the five high-precision mirror elements of the ELT. In addition to the segmented 39-meter giant mirror, ...

The resolving power is thus 2.6 times higher than that of the largest solar telescope to date, the Big Bear Solar Observatory near Los Angeles, which also uses a primary mirror made of ZERODUR®.

Zerodur ® Zerodur ® is a glass ceramic manufactured by Schott using a process known as controlled volume crystallization. The structure contains 7-78% of high quartz micro-crystallites 30-50 nm in ...
