Laser-Driven Light Source (LDLS)
EQ-99X-QZ-S
The EQ-99X-QZ-S is a standard LDLS model with a diverging-beam optical interface. It has a compact lamphead with lower heat generation that makes it ideal for experiments in cramped spaces or for installation into equipment. The lamphead is designed to cool by natural convection thus eliminating vibrations caused by cooling fans and ensuring a highly stable light output.
Features
- Extremely broad wavelength range：170 nm to 2500 nm
- Long lifetime：10 000 hours
- High radiance from a small plasma

1. What are cookies?
For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently.

Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive.
