Hot Mirror - Type SHM - Professional Grade
Hot Mirror - Type SHM - Professional Grade
Coursen Coating Labs Inc., United States
REQUEST A QUOTE
Hot mirrors are used to reflect the IR (heat energy), while transmitting the visible light, and blocking UV light. Typically used anywhere that visible light must be cooled. Hot mirrors are often used in conjunction with cold mirrors. Applications include motion picture projectors, projection TV, endoscopes, microscopes, and exotic sun glasses.

Chirped Mirrors & Dispersive Coatings for Ultrafast Lasers
Chirped Mirrors & Dispersive Coatings for Ultrafast Lasers
LASEROPTIK GmbH, Germany
REQUEST A QUOTEVISIT WEBSITE
As part of our recently enlarged program for ultrafast laser applications, LASEROPTIK offers chirped mirrors, matched pairs and dispersive coatings. In addition, the use of high quality substrates with superior roughness from our Premium (<2Ȧ rms) or super-polished (<1Ȧ rms) product line helps to achieve lowest losses for these critical components. A variety of standard sizes is available from stock. For example, chirped mirrors compensate for the dispersion introduced by other elements like the laser crystal in a laser cavity. Or they serve as compressors in chirped pulse amplification systems (CPA). They include types like • mirrors with low or optimized GDD, • GTI mirrors, i.e. highly dispersive narrow bandwidth mirrors, • chirped mirrors and matched mirror pairs, • octave-spanning broadband chirped mirrors with moderate GDD, • partial reflectors, • coatings used within an OPO. In general, various spectral requirements can be combined with a GDD value as target for coating design and production, e.g. for OPO optics or partial reflectors. The dispersion management is highly depending on the coating design and a sub-nanometer manufacturing accuracy for GDD optimized optics. At LASEROPTIK, this precision is ensured by the sophisticated method of Ion Beam Sputtering (IBS). With the help of an optical in-situ process control based on the calculated design, the deposition of complex, custom tailored stacks of many (n > 70) non­quarterwave layers is performed. The results are verified ex-situ by in-house GDD measurements.

Extremely Low Loss Laser Optics
Extremely Low Loss Laser Optics
LASEROPTIK GmbH, Germany
REQUEST A QUOTEVISIT WEBSITE
For any application which requires coated optics with extremely low losses LASEROPTIK manufactures mirrors with R > 99,998 % and total losses < 10 ppm. These so called supermirrors are used in ring laser gyroscope assemblies or certain scientific and commercial applications. LASEROPTIK uses modified IBS machines that are capable to produce low absorption and low scatter coatings on super polished substrates. The cleanliness of these machines and environment is maintained in dedicated super-clean rooms, where also the extensive substrate pre and after treatment takes place. Measurement devices such as white light profilometers and high resolution microscopes for the inspection procedures are in place. A custom built cavity ring-down setup allows to determine the reflection with a precision of up to four decimal places and to refer back to the losses. The use of super polished substrates with a surface roughness < 1 Å rms is essential for the values mentioned above. Their quality is inspected with a white light profilometer to assure best performance of the finished mirror.
