Product Details

The inline filter holder is a convenient sampling accessory that connects to optical fibers on either side of the holder.

With the INLINE-SFH, users can measure optical filters from 10-12.7 mm diameter and up to 9 mm thickness by connecting one end of the holder to an illumination fiber (transmits light from a source) and the other to a read fiber (transmits light to the spectrometer).

The INLINE-SFH is permanently aligned during production so there is no need for additional adjustments. It has room for up to 9 mm thickness of filters, enabling the use of up to 3 filters at one time.

Product Overview

  • Filter transmission – accepts standard optical filters from 10-12.7 mm diameter and up to 9 mm thickness
  • Flexible – accepts up to 9 mm total thickness of filters (e.g., three 3 mm thick filters)
  • Simple to use – permanently aligned, no adjustments required
