The pairs of etalons have matched surface figure that exceeds λ/100. They are marked to indicate the matched orientation. They are ideal for customers that are setting up there own Fabry Perot etalon cavities and want the flexibility of using there own mounting system.
- Clear apertures: > 85%
- Front Surface Matched Figure: λ/100 or better
- Front Surface Figure: λ/20 or better
- Surface Quality: 10/5 or better
- Wedge: 30 minutes (to avoid reflections)
- Material: Fused Silica
- Coating: Uncoated

FSR Nominal Thickness Finesse Detailed Drawing Price Buy Now Solid silicon etalons are interesting because the high index of silicon (3.4 depending on wavelength) creates a reasonably high finesse without any coatings. The temperture sensitivity of silicon can also be useful (or problematic).
- Material: Silicon
- Wavelength range: IR 1.2um to 6.3um
- Wedge < 5 arc seconds*
- Clear aperture: 85% of diameter for lengths < 1cm
- Clear aperture: 5mm for lengths > 1cm
- Surface quality: 10/5 or better
- Matched surface figure: λ/50
- Diameter: 25.4
- Finesse and FSR are dependant on the wavelength (see Refractive index for various materials)
- FSR shown is calculated for 1545nm
- Thickness: see table
- Please contact us for any custom requirement
- * If your etalons require coatings then we can us our fluid jet polishing system reduce the wedge and increase the finesse
FSR Finesse Detailed Drawing Price Solid YAG etalons are also handy because the high index of YAG material (about 1.8 depending on wavelength). This creates a reasonably high finesse without any coatings, this makes yagalons excellent for mode selection in high power solid state lasers. The additional advantage of YAG is excellent transmission in a wide range a wavelengths.
- Material: Undoped YAG
- Wavelength range: 250nm to 4um
- Wedge: Less than 1 arc second typical
- Clear aperture: 85% of outside dimension
- Surface quality: 10/5 or better
- Matched surface figure: λ/50
- Diameter: 5.0mm or 1/2"
- Finesse and FSR vary with wavelength, FSR below is bases on an index of 1.82
- Thickness: see table, please contact us regarding custom sizes and thicknesses and specifications
