Standard fixed holders
Description
These holders provide a much more secure mounting than adjustable types and are also more compact. They grip the optical component gently but firmly all around its perimeter, without obscuring the useful aperture. The threaded retaining ring has a knurled lip which protrudes from the mount and can easily be turned by hand without a special tool. For alternative slotted rings see MW range.
The ranges are based on four standard bodies, accepting the commonest lens diameters of 16mm, 25mm, 40mm and 50mm. Other holders listed comprise one of these bodies supplied with a pair of lens-size adaptors (see product group MR) to accept the diameter listed. Other adaptors can of course be supplied at relatively small cost, (see product group MR), making the system much more versatile and economical than holders limited to one size only.
The basic HD series have a fixed one-piece body and are the very economical.
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.
• Secure grip around lens edge
• Minimal obscuration of aperture
• No special tool required
• No stray light around lens edge
• Component edge thickness 0–9mm
