WHAT IS
COATING?
 |
 |
Thin film coating is a vacuum deposition procedure used to enhance the transmissive properties of an optical surface. The most common types of dielectric coatings are anti-reflection and high reflection coatings, but beam-splitter, band pass filter, edge filter, and polarizing coatings are also available. Because thin film coatings are more durable than optical glass, coatings also help protect an optic surface from scratches and the environment. |
MANUFACTURING
TECHNOLOGY
|
Optimax currently has four electron-beam
gun box coaters. An ion-assisted deposition process is used to enhance adhesion and durability while minimizing spectral shift. We control film thickness with a quartz crystal monitoring system. Optimax cleans optics in a Class 10,000 environment. We also have a Class 100 assembly area for high-energy laser optics. |
 |
IN-HOUSE
COATING CAPABILITIES
|
| Optimax produces optics up to 300mm in diameter with a wide variety of narrow and broadband anti-reflection coatings including doublet interface coatings. Both metal and dielectric mirror coatings are also available. For custom coatings, we utilize TFCalc thin film design software. Please see the reverse side for sample reflectance curves. |
QUALITY
ASSURANCE
|
| Optimax performs test runs of all coatings before beginning production to ensure a good design. We use a Perkin-Elmer Lambda 900 Spectrophotometer to check the performance of the coating upon completion. Adhesion, abrasion, and humidity tests are available
to verify coating durability in accordance with sections of MIL-C-675C, MIL-C-48497A, and MIL-C-13508C specifications. Laser damage testing is also available upon customer request. |

OPTIMAX
COATING PERFORMANCE
|
| The sample coating curves listed below include MgF2, single and dual wavelength anti-reflection, broadband anti-reflection, and both metal and single wavelength dielectric mirror coatings. These coatings can be modified for specific wavelengths, angles, and polarizations to meet project requirements. |
