1. Product Description

The Bios series high stability diode laser source of Elite adopts high-performance LD, has stable wavelength and high output power. Available wavelengths from ultraviolet to infrared(375~785nm).

The control system based on the advanced microprocessor, together with the high-precision ATC and ACC control circuit can realize the stable output and ensure the simplicity and immediacy of the operation simultaneously.

Elite can offer the corresponding communication interface and control software according to the requirement of the user in order to achieve computer control.

Bios series products include Free Space Laser and Fiber Coupled Laser(SMF Fiber Coupled Laser with FC or SMA 905 connector), both offer highly customized services.

Free Space Bios series is available in two sizes:

1.The standard size:(L)80mm X (W)38mm X (H)45mm

2.The mini size:(L)55mm X (W)33mm X (H)32mm

Low Noise Laser

The noise issues of lasers are due to the competition of mode in laser resonant cavity, which lead to high frequency jitter of output power. Through special design for laser resonant cavity and other components, the laser amplitude noise can be reduced efficiently.

Elite low noise laser can be widely applied to DNA sequences, cell sorting, spectrum analysis, interference measurement, laser holography, photo processing and biomedical and other fields.
