Swing Prism Borescopes

Rigid borescopes which direction of view can be adjusted continuously from fore-oblique to retro viewing-coupled with the field of view, this allows a total viewing arc of 120°to 140°. Some applications require the observation of a wider area that can be achieved using a single rigid instrument.

Some applications require the observation of a wider area that can be achieved using a single rigid instrument. Standard rigid borescopes have a fixed direction of view and a fixed field of view, which although perfectly suited to a single area inspection, can necessitate a kit of multiple instruments to fully inspect a larger area.

The Swing Prism borescopes feature an adjustable prism in the objective end of the instrument that allows the operator to remotely control the direction of view from 45° fore-oblique to 115° retro, thus allowing the area to be 'scanned'. Coupled to the standard 50° field of view of the instrument, a total arc of 120° can be viewed. In addition, the light guide fibers at the objective end are separated to provide a spread of illumination across the entire viewing range.

All the optical innovations of conventional Olympus standard rigid borescopes are also incorporated in the Swing Prism design.

Swing Prism Borescopes


Sophisticated optical system

Olympus is renowned for optical innovation and the standard borescope is no exception. Each diameter of borescope has it own lens system design, optimized to the available space. Multi-layer lens coating is used to reduce internal reflections and maximize image brightness and contrast.

Swing prism mechanism

The scope direction of view can be adjusted continuously from 40 degree fore-oblique to 115 degree retro viewing - coupled with the field of view, this allows a total viewing arc of 120 degree, from 20 to 140 degree.

Orbital scan

Especially useful when the borescope is clamped or being used in conjunction with CCTV, this feature allows the insertion tube to be rotated a full 370 degrees without affecting the orientation of the control body or accessories attached to the eyepiece.

High-grade stainless steel insertion tube

Ensures a durable, corrosion free, fluid resistant, outer protective sheath.

Laser welded tip

Significantly reduces the possibility of tip detachment for safe, trouble free inspections.

Ergonomically designed control body

A comfortable and functional control body design has always been a hallmark of Olympus borescopes. The Series 5 design further enhances this and integrates all controls, placing them within easy reach for true single handed operation.

Color coded identification ring

The serial number and model reference are engraved in the eyepiece ring. This is also color coded to indicate the borescope direction of view.

Lens to fiber ratio

While large lenses provide bright, clear images in ambient lighting conditions, the overall result in an actual inspection is far more dependant on the light transmission performance of the instrument. Standard rigid borescope achieves a precise balance of lenses and fibers for superb image brightness.

Digital Camera Systems OM Adapters

Digital Camera System OM Adapter

These adapters allow you to connect industrial fiberscopes or rigid borescopes to selected Olympus digital SLR cameras or mirrorless ones*1. This makes it easy to transfer images to a computer and for creating archives of inspection histories.

*1: The optional OM adapter MF-1 or MF-2 is required to connect the OM adapters listed below to the digital SLR cameras or mirrorless ones.
