Laser Spot Size Calculator

Notes:

• Please use the American standard for number formatting rather than the European standard (i.e. for "two and a half," enter "2.5" rather than "2,5").
• This list is updated periodically and may not reflect our most current laser and laser diode product offerings.

Description

Determine spot size of our lasers and laser diode modules from user supplied working distances. Calculator provides circular or elliptical spot size approximations based on 1/e² beam diameter and beam divergence; for lasers, beam diameter is given for TEM₀₀ mode. Spot size visibility varies based on ambient light conditions.
