Secomam UVIKON XS UV-Vis Spectrophotometer, 190–1100 nm, 1.8 nm Bandwidth, P/N 70/ 99-9028

The Secomam UVIKON XS UV-Vis spectrophotometer is a true symmetric double-beam instrument designed for precise, stable absorbance measurements across a 190–1100 nm wavelength range. Its fixed 1.8 nm bandwidth and Advanced Digital Signal Processing technology support reliable data acquisition, low instrument noise, and linear measurements at high optical density values.

• 100% symmetric true double-beam optical system for enhanced measurement precision and stability
• High-energy diffraction monochromator based on a Zeiss™ design
• Holographic blazed grating with 1,300 lines/mm
• Sensitive photodiode detector with rotating all-reflective chopper mirror
• Sample and reference beams receive 100% energy, with dark-current correction
• Quartz windows at the sample-compartment beam entrance and exit help protect the optics from contamination
• Optical bench thermally insulated from the external source bench
• Photometric assembly isolated from ozone produced by the deuterium lamp
• Optical bench base manufactured to a tolerance of 0.01 mm over 1 meter
• Fully sealed optical system protects against dust and volatile atmospheric compounds
• Removable front, top, and rear covers provide convenient access for maintenance
• Three-point accessory positioning supports reproducible measurements
