Sigma optical UV achromatic lens

Product Introduction

A lens with NA below 0.1 has a focal spot diameter almost close to the diffraction limit for collimated laser imaging.
Not using glass or adhesive that absorbs ultraviolet light, it has good light resistance.

▶ Undertake the manufacturing of high-energy pulse lasers or products with specified wavelengths outside of the product catalog.
▶ According to customer technical specifications, hundreds of orders of magnitude can be produced in bulk.
▶ For the focal length of each wavelength, please refer to the [Relationship Table of Focal Length with Wavelength] on the webpage.

▶ A spotlight lens enables an infinitely distant object to be imaged at the focal position, or converts a point light source into parallel light. If we want to image objects at close range, the optical performance of the lens will not be fully utilized.
▶ The incident light must enter the condenser lens from the specified direction, and the parallel light must be incident into the lens from above (engraved with upright text). If the incident light enters the lens from the opposite direction, it will cause color difference or spherical aberration to deteriorate, the focal spot will become larger, and the image will be blurred.
▶ When used under conditions outside the designed wavelength, it leads to deterioration of color difference and a decrease in transmittance.
▶ When using high-power lasers or near heat sources, it may cause an increase in the temperature of the condenser lens and a change in focal length. If used for a long time, good heat dissipation measures must be taken.
▶ The surface reflection of the lens (3% to 4%) will result in a transmission loss of approximately 13%.
