HTL Type S Borosilicate Outer Filter

is a replacement outer filter for the Atlas Ci5000 Weather-Ometer. 

Applications

Traditional Daylight Weathering

When paired with a Type S borosilicate inner filter, the outer filter supports a traditional daylight or Daylight Type II spectrum for accelerated xenon-arc weathering.

Extended UV Exposure

When paired with a quartz inner filter, the same outer filter produces an Extended UV spectrum with more short-wave ultraviolet radiation than natural sunlight.

Automotive Material Testing

The Quartz/Type S borosilicate configuration may be used as part of compatible Ci5000 setups for specified SAE and automotive exposure procedures. Confirm the complete filter arrangement, instrument settings, and current method revision before testing.

Research, Quality Control, and Product Validation

The filter supports material-development, comparative durability, production quality-control, and product-qualification programs across traditional daylight and Extended UV exposure conditions.

Features

• Supports two distinct exposure spectra through the selection of the compatible inner filter.
• Allows traditional daylight and Extended UV testing without changing the outer-filter part number.
• Provides direct compatibility with the Atlas Ci5000 Weather-Ometer.
• Helps maintain controlled spectral conditions for repeatable weathering and materials-testing programs.

Specifications

Published Irradiance Ranges

The following values apply to complete Ci5000 lamp and filter configurations using the Type S borosilicate outer filter. They describe the combined lamp, inner filter, outer filter, instrument condition, and operating settings rather than the outer filter by itself.

Published ranges may vary with lamp age, instrument condition, laboratory environment, facility infrastructure, and operating settings. Confirm the required inner filter and current test method before selecting exposure conditions.
