Introduction
1. Product Overview
UV Solar Simulators are designed for demanding photobiology applications, delivering standards-compliant UV output across the entire sampling area. They feature a patent-pending optical design that ensures non-uniformity of irradiance below 5% and allow adjustable output from 10% to 100% of the maximum solar constants using an integrated attenuating device. These simulators are ideal for SPF testing, photo-toxicity, photo-allergy, photo-carcinogenicity, and photo-genotoxicity studies.

Optional Digital Exposure System for enhanced temporal stability
Optional electronic shutter with TTL input
6. Operation and Maintenance
Operation
Power on the simulator; electronics and lamp settings are pre-configured
Adjust output irradiance using the integrated variable attenuator
Use the manual shutter or optional electronic shutter to control beam exposure
Position the simulator at the specified working distance for accurate solar constants
Maintenance
Inspect lamp and filters periodically; replace lamps after ~1000 hours of spectral-compliant operation
Keep the housing, optics, and filters clean for consistent output
Ensure fan and filter systems are functional to maintain optimal operating temperature
Verify temporal stability and irradiance uniformity periodically
