This is a special laser pointer which emits at the unique golden yellow wavelength of 591nm.

These have recently been upgraded with new modules! This means your laser will be around twice as powerful as our older models, with better stability as well.

591nm is an amazing yellow color, with the additional property of being the single best color to use for star-pointing and astronomy! It’s the perfect wavelength to have a beam visible to our color vision without hindering our night vision.

This color is very close to existing 589nm yellow lasers, but just a bit more amber. It’s a truly stunning color to look at.

Since this is a DPSS laser, it has excellent beam specs, with great divergence. However, these are not incredibly powerful lasers - the DPSS technology used is very new, and can’t yet achieve enough power to burn anything.

These lasers are somewhat temperature-sensitive; occasionally they may emit green light for a brief period while in the "warm-up" phase. If the batteries are fully charged, you should see yellow output very quickly. Our new upgraded units (since August 2023) are also more stable, and respond much better to temperature differences.

Listing includes one 591nm laser, one rechargeable cell, one battery charger. Battery is inserted with the negative side first!
