Optical Filter for Fluorescence Contact Imaging

A scientists contacted us to use ZnTe wafer as an optical filter for fluorescence contact imaging. Requirements: ZnTe, any orientation, undoped, 2sp, <=0.5mm thick.


5x5mm later dimensions would work. Are the wafers that are less than 0.5mm thick fabricated on a substrate such as fused silica or do they? We would like the thinnest you normally fabricate or have in stock. I see you have done down to 0.1mm thick in the past. 

Cost estimate? Lead time?

UniversityWafer, Inc. Quoted:

ZnTe, (110), 5x5x0.5 mm
ZnTe, (110), 5x5x0.3 mm
ZnTe, (110), 6x6x0.2 mm
ZnTe, (110), 5x5x0.15 mm

All plates are free-standing, i.e., are not glued to the support plates.


Warning: ZnTe contains microbubbles (see photo below), we don't regard bubbles as a ground for the complaint.

A crystal of such material is subjected to a high-intensity light pulse of subpicosecond duration, it emits a pulse of terahertz frequency through a nonlinear optical process called optical rectification. Conversely, subjecting a zinc telluride crystal to terahertz radiation causes it to show optical birefringence and change the polarization of a transmitting light, making it an electro-optic detector. Zinc telluride, "ZnTe", is a non-linear optical photorefractive material of possible use in the protection of sensors at visible wavelengths. ZnTe optical limiters are light and compact, without complicated optics of conventional limiters. ZnTe can block a high-intensity jamming beam from a laser dazzler, while still passing the lower-intensity image of the observed scene. It can also be used in holographic interferometry, in reconfigurable optical interconnections, and in laser optical phase conjugation devices. It offers superior photorefractive performance at wavelengths between 600–1300 nm, in comparison with other III-V and II-VI compound semiconductors.
