Product Description

Product Introduction

Product Features

1. Light Source System

Automatic 8-lamp turret with automatic optimization and alignment, supporting 2 positions for high-performance lamps.
Simultaneous 8-lamp power supply with preheating capability, ensuring stable light output.
Freely editable lamp position memory function, eliminating the need for coded lamps.

Optical System

Czerny-Turner monochromator with a high-resolution diffraction grating (1800 lines/mm).
7 selectable spectral bandwidths, with automatic setting and optimization.
Rigid cast optical platform with ultra-low deformation under high/low temperature conditions, ensuring long-term stability.
Dual-beam optics to effectively suppress baseline drift, reduce warm-up time, and improve accuracy.
