Type S Borosilicate Inner Filter

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

Applications

Accelerated Outdoor Weathering

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

Indoor Lightfastness Testing

When paired with a soda-lime outer filter, the Type S borosilicate inner filter helps reproduce sunlight transmitted through window glass for evaluating fading, color change, yellowing, cracking, and other light-induced effects.

Automotive Interior Exposure

Specified configurations may combine the Type S inner filter with a soda-lime outer filter and auxiliary float glass for automotive interior trim exposure programs. Confirm the complete filter arrangement, auxiliary lantern, and operating cycle required by the applicable method before testing.

Research, Quality Control, and Product Validation

The filter supports established xenon-arc procedures used in material development, comparative durability testing, production quality control, and product qualification. Selecting the correct outer filter is essential because it determines the resulting exposure spectrum.

Features

• Supports multiple exposure environments through compatible traditional-daylight, window-glass, and specialized auxiliary-filter configurations.
• Helps maintain controlled spectral conditions for repeatable Ci5000 weathering and lightfastness programs.
• Clearly differentiates traditional daylight and window-glass testing from Extended UV and closer natural-daylight alternatives.

Specifications

Published Irradiance Ranges

The following values apply to complete Atlas Ci5000 filter configurations using the HTL Type S borosilicate inner filter. They describe the combined lamp, inner filter, outer filter, and instrument system rather than the inner filter by itself. Published values are based on a 5,000–14,000 W lamp-power range.

Published ranges are based on complete instrument configurations and may vary with lamp condition, laboratory environment, facility infrastructure, and instrument condition. Confirm the required outer filter, auxiliary components, and test method before selecting operating conditions.

FAQs

Which instrument is compatible with the HTL Type S borosilicate inner filter?

The Type S borosilicate inner filter is designed for the Atlas Ci5000 Weather-Ometer. Confirm the instrument model and existing component part number before ordering.

Can the Type S borosilicate inner filter be used for automotive interior testing?

Yes, when the applicable method specifies a compatible configuration. Atlas documents arrangements using the Type S inner filter, soda-lime outer filter, and auxiliary float glass for selected automotive interior exposure programs.

How often should the Ci5000 inner filter be replaced?

The Type S borosilicate inner filter should be replaced after 400 operating hours. 

What is the difference between this filter and the Ci5000 quartz inner filter?

The Type S borosilicate inner filter supports traditional daylight or window-glass configurations depending on the outer filter. The quartz inner filter is used for Extended UV exposure and should not be substituted without confirming the required test spectrum.
