Oriel strives to furnish our customers with the latest in
photonics technology, both modern instruments and
innovative optical components. Our new Microlens Arrays
fall into the second category. The lenses listed on this page
can be used in a wide variety of applications; for example:
•Beam homogenizing
•Fiber coupling
•Brightening of miniature displays
•Efficiency improvements in focal plane arrays
Each microlens array comes centered on a 1 inch
(25.4 mm) diameter glass substrate. Here we offer a variety
of standard products for experimentation or development,
plus we can provide economical custom pieces in larger
quantities. Please call an Applications Engineer to discuss
your particular specifications.
SQUARE OR HEXAGONAL
We offer two array patterns, in various array sizes. The
