Santec built the world’s first commercially available narrow linewidth tunable laser source in 1987. The optical design of the Santec TLS-510 focuses to gain better signal to noise ratio. It achieves over 65dB STSSE and over 70dB SSSE. It is essential for measuring large dynamic range of wavelength profile without affected by noise of the light source.

Four models

The Santec TLS-510 range has four versions:
Type A　：　Standard model with +10dBm or more peak output power
Type B　：　Low noise model with high SNR(Signal to Noise Ratio) of 65dB or more
Type C　：　High wavelength accuracy model of ±5pm or less with built-in wavelength monitor
Type D　：　Low noise (High SNR) and high wavelength accuracy model
