A unique color of laser pointer. Very similar to deep red lasers we are accustomed to. This laser pointer has terrible beam divergence due to it's multimode diode characteristics. The focused point is a small line rather than a point. This laser is not a good burner, but perfect for collecting unique wavelengths.
