Coatings

ANTIREFLECTION

Single Layer MgF

Applied  to materials with   reflective indicies from 1.45 to 2.4. The most  popular antireflective coating   for visible wavelengths. It is  insensitive to change in incidence angles.

Multilayer "V"

Used  to provide low reflectance   within a narrow durable wavelength band  for most laser applications. Minimum   reflection can be less than 0.1%.

Broadband Multilayer

These  coatingshave excellent   performance over a broad special broadband.  Coating performance is sensitive   to angle of incidence.

Dual Wavelength Band

Offer very low reflectance at two   widely spaced wave lengths, such as Nd: YAG Laser (1064) and its second   harmonic (532).

PARTIAL REFLECTION

Narrow Band

Provide  50% reflection and   transmission at an angle of 45° incidence for a  single wavelength. Perfect   for beamsplitter applications.  Transmission/reflection (T/R) ratio of 20/80.   Additional T/R ratios  for beamsplitter are available upon request.

Broadband

Provide  50% reflection and   transmission over a wide bandwidth. JH OPTEK also  provides coating with   different R/T ratios and specific angles of  incidence.

BEAMSPLITTER

Laser Line Polarizing   Beamsplitters

High reflection for s-polarized   and reflection for p-polarized for laser applications.

Broadband Polarizing   Beamsplitters

Wide wavelength bandwidths   provide high reflection to s-polarized and antireflection to p-polarized.

Dichroic Beamsplitter Mirrors

These  coatings separate the laser   fundamental and the pump wavelength or  the fundamental and the second   harmonic. They are specifically applied  to laser mirrors.

DPSS LASERS

Diode Pumped Laser Optics   Coatings (DPO)

These  coatings are designed for a   diode pumped laser. They can be deposited  on a variety of substrates and have   a high damage threshold.

HIGH REFLECTION

Dioeletric High Reflective   Coatings

Provide high reflectance over a   broad bandwidth and are ideal for tunable laser or white light applications.

Metallic High Reflective Coatings

Metallic  coating have low peak reflectance,   mechanical durability and a high  damage threshold, but they have an extremely   broad bandwidth and low  cost. They are insensitive to angle of incident light   and  polarization.
