Design Considerations
We design and produce filters for many different applications. Each application has specific, often complex and demanding, requirements. The level of performance attained in an optical system depends upon the integration of the filter design with the performance of other system components. This section addresses the most important system characteristics as related to filter performance.
Extended Attenuation:
- Signal-to-Noise Ratio
- Filter Orientation
- Incident Power
- Angle of Incidence & Polarization
- System Speed
- Temperature Effects
- Humidity Effects
- Filter Life
- Transmission & Optical Density
- Image Quality
- Optimizing Custom Filter Sets
- Physical Configurations
- Coatings & Special Substrates
Omega Optical employs the use of 23 active coating chambers and has always utilized a wide variety of coating technologies for complex high-phase thickness thin films. We utilize Physical Vapor Deposition PVD) with resistive element heating, Ion assisted e-Beam, and Dual Magnetron Reactive Ion Beam Sputtering; the world’s most advanced sputtering technology. No single technology is ideal for every application. As a world-class manufacturer, Omega Optical knows the attributes and limitation of each and utilizes multiple technologies to achieve best results.
In addition, we consider the following to be important considerations when recommending or designing the filter that’s right for your instrument development: angle of incidence, polarization, substrate material, system speed, and temperature effects.
We have our own in-house optical polishing, grinding & configuring machine shop, and can supply filters in physical dimensions of:
5mm-215mm
Round, square, rectangular
Standard Dimension Tolerances +0/-0.2mm
Custom / Non-Standard Configurations Available
