Frequently Asked Questions

The center thickness of the Fused Silica glass wedge pair is 1.4mm or 2.0mm, and the wedge dimensions are 35(W) x 20(H)mm or 50(W) x 25(H)mm with a wedge angle of 4°. The surface is less than lambda or lambda/10, and the S-D is less than 60/40.

The center thickness of the CaF2 glass wedge pair is 1.4mm, and the wedge dimensions are 35 (W) x 20 (H)mm with a wedge angle of 4°. The surface is less than lambda/6.

The glass wedges are used for dispersion compensation, fine tuning, and optimal compression in combination with dispersion compensating mirrors such as the DCM range.

The achievable dispersion characteristics are easily computable via vCHIRP, and the glass wedges can be used un-coated under Brewster's Angle.

Yes, a wedge holder is available as an optional accessory. Different dimensions are also available upon request.
