Laser diode devices in industry are rated in general for 50,000 hours mean time before failure under standard environmental conditions. Temperature control and cooling can help in prolonging laser diode life—in most cases, a relatively cool laser diode is a healthy, happy diode. Although DIMETIX USA offers internal heaters for use in cold climates, warm climates may pose a challenge. Fortunately Dimetix lasers are rated operationally up to 50⁰C, which is more than sufficient for most environments. The lasers generate about 5⁰C of heat internally, however, so 45⁰C should be considered the upper environmental temperature limit.
