Abstract
The invention is directed to a double refracting planar plate arrangement and a .lambda./4 plate suitable for deep ultraviolet light. The .lambda./4 plate or the like is configured as a planar plate with stress-induced birefringence. The planar plate 1 is made of high quality quartz glass and is torsion-free and uniformly loaded in tension via suitable construction having several parallel tension devices (3, 7).

A double-refracting planar plate arrangement having stress-induced birefringence, the arrangement comprising:
- a planar glass plate having first and second ends lying opposite each other;
- and,
- a first plurality and a second plurality of mutually decoupled parallel tension devices connected to said first and second ends, respectively, for applying first and second tension forces thereto and for holding said planar glass plate under uniform tensile stress without imparting a compressive stress thereto.
A double-refracting planar plate arrangement having stress-induced birefringence, the arrangement comprising:
- a planar plate having first and second ends lying opposite each other;
- a first plurality and a second plurality of mutually parallel tension devices connected to said first and second ends, respectively, for applying first and second tension forces thereto;
- said planar plate having an optically useable mid region between said first and second ends;
- said first and second ends defining first and second coupling regions at which said first and second pluralities of tension devices apply tension forces;
- and,
- first and second pairs of transverse bars adherent to said planar plate between said mid region and said first and second coupling regions, respectively.
A double-refracting planar plate arrangement having stress-induced birefringence, the arrangement comprising:
- a planar plate having first and second ends lying opposite each other;
- a first plurality and a second plurality of mutually parallel-tension devices connected to said first and second ends, respectively, for applying first and second tension forces thereto;
- and,
- at least one of said tension devices including a tension spring.
