In many cases, replicated optics can directly replace conventional optics, lowering system costs. We replicate the surface of a master optic (original) onto a low-cost substrate, using our proprietary technology.
- Aspheric Surfaces
Plano, spherical, aspherical, and cylindrical surfaces can be replicated in OEM quantities, making replication an attractive approach to fabricating a wide range of high-quality optical components. Holographix can also replicate diffractive optics onto refractive surfaces, providing diffraction-limited performance from a single optical element.
General Replica Properties:
|Wavelength range:||190 nm to 15 µm;|
|Flatness/curvature:||to < 1/20 wave|
|Dig and scratch:||to 20 - 10|
|Temperature range:||-50° C to 200° C|
|Humidity range:||0 to 95% continuous|
|Chemical resistance:||most common solvents|
- Our customers achieve cost savings by:
- the use of low cost substrates
- integrating low cost mounting and alignment features into the blank
- reducing the number of assembly steps necessary to integrate the optic into the system
- Replicated mirrors on metals
- readily machinable materials are used as substrates
- blanks are typically lower cost compared to glass
- provide both design and manufacturing flexibility by eliminating glass mirror / metal mount assembly
- Replicated aspherics
- typically use low cost spherical blanks
- can be used as transmission or reflection elements
- provide aberration corrected performance using a single optical element
Replication minimizes system cost, reduces weight of the final component, and significantly simplifies system design by eliminating glass mirrors and placing the mirror surface directly onto the metal mount.
Because readily machinable materials such as aluminum and beryllium can be used to produce replica substrates, custom mirrors can be produced with pre-machined alignment tabs, mounts and other design features required for direct assembly into the final system. The use of replicated mirrors provides both design and manufacturing flexibility at a lower unit cost than conventional glass mirrors.
Aspherics may be replicated onto various surfaces either for use in transmission or reflection. In a typical case, replication of an aspheric surface onto a standard spherical surface significantly reduces cost of final component when compared to grinding and polishing. The final product provides aberration corrected performance using a single optical element.
