Frequently Asked Questions

Sapphire IPL Filters are used as key optical elements for IPL machines, which filter the UV wave and reserve the useful wave from 400nm to 1200nm for cosmetic laser treatments such as photorejuvenation, hair removal, vascular and acne treatment.

Sapphire IPL Filters are available in wavelengths of 400, 420, 460, 490, 515, 530, 550, 560, 570, 590, 615, 645, 695, 755, 780, and 810nm.

The surface quality of the input and output surfaces of Sapphire IPL Filters could be S/D: 20/10, and flatness λ/10 is available.

The typical materials for Sapphire IPL Filters are sapphire, BK7, fused silica, B270, and so on.

The dimensions and tolerances of Sapphire IPL Filters are ±0.05mm for dimension tolerance, 10/5 for surface quality, <1arcmin for parallelism, <λ/10 for flatness (per 25mm @ 633nm), and <0.25mm for bevel (face width X 45).
