Ring-mounted holders
Description
The ring-mounted HR series consist of a lens cell (similar to the MB series) clamped in an outer ring. The lens and cell can be released, rotated or translated axially (range about 10mm) and clamped in any position. For smoother continuous movements, see graduated rotating holders (basic & precision) and rotating holders.
• Secure grip around lens edge
• Minimal obscuration of aperture
• No special tool required
• No stray light around lens edge
• Component edge thickness 0–9mm
The table on this page relates to type HR, for product types HD see our Standard fixed holders section.


The threads used are those of the TubeMount system and can also be used to attach other TubeMount elements. Spacers or extra retaining rings can be used to mount several components in one holder.
