LDI-7 Laser Diode Illuminator
LDI-7
The LDI is a multiline, solid-state laser illuminator offering up to 1000 mW of output power per laser line via a multimode fiber, at the price of lower power LED light engines. Feedback-controlled output stability and up to a 100:1 linear dynamic range make the LDI the ideal light source for a wide range of applications, including spinning disk confocal microscopy, structured illumination microscopy, FRAP, and photoactivation/photoconversion. Note that we can also work with you to provide solutions for your unique needs.
Key features
- 7 laser lines across the full visible spectrum (405 nm to 640 nm)
- Up to 1000 mW output power per line
- No user alignment required
- TTL & Analog control
