General Description
ECI
offers several multilayer and metal beamsplitter coatings
designed specifically for plastic substrates. These vacuum-deposited
thin films offer precision optical grade performance on
acrylic, polycarbonate and other low temperature substrates.
These films are used in applications where an incident
light source must be split into two separate beams.
The
metal beamsplitter coatings (#3535) offer reduced
cost and a very neutral spectral performance at the expense
of some coating absorption. These films typically have
35% reflection, 35% transmission and 30% absorption. They
also offer the advantage of maintaining a neutral spectral
balance over a wide angular range.
The
multilayer designs (#5050) are non-absorbing, all
dielectric thin films that offer the designer total light
efficiency. Designs are available within the 300 to 1600
nanometer wavelength region in reflection/transmission
ratios from 5/95 up to 95/5. We can advise you of the characteristics
and performance of one or several possible designs for
your particular application.
Applications
This family
of thin films has many possible uses in a wide variety
of applications including Heads-up displays, sensors, laser
alignment, fiberoptic devices, medical imaging and vision
systems. Contact one of our sales engineers to discuss
your particular needs and take advantage of our free in-house
design service.
