Rigid endoscopes

ELTROTEC rigid borescopes were developed for the visual inspection of small bore holes and cavities. With diameters ranging from 0.7 to 25mm, they offer excellent image reproduction and with their excellent resolution and brightness facilitate the inspection of the smallest details. The Top-Line premium endoscopes are equipped with graded index lenses (GRIN lenses), providing the highest quality with no appreciable image loss.

High quality lens systems provide clear and sharp images with perfect resolution. From the variety of different viewing directions and opening angles, you can choose the most suitable model of the SKF-D series for your application. On models with lateral viewing direction the probe can be rotated. Thus the position of the internal part to be tested is irrelevant. Due to the offset focus ring and the possibility to unscrew the eye funnel, the endoscopes are ideally suited for use with a camera. The object is illuminated by an external light source
- Ø from 1 mm to 8 mm
- Perfect optical system
- Optimized light conductors for excellent image brightness
- External focus ring for diopter adjustment
- Rotatable probe

The Eltrotec MKF-D is unique thanks to its continuously swiveling lens from -7° to 133°. The entire region in front of the endoscope can be inspected by moving the prism. With the 370° rotatable probe no detail remains hidden. High quality lens systems provide clear and sharp images with perfect resolution. Due to the offset focus ring and the possibility to unscrew the eye funnel, the endoscopes are ideally suited for use with a camera. The object is illuminated by an external light source.
- Ø 6, 8 and 9 mm
- Continuously swiveling lens from -7° to 133°
- Perfect optical system
- Optimized light conductors for excellent image brightness
- External focus ring for diopter adjustment
- Probe rotatable by 370°

The panoramascope enables time-saving inspection of cylindrical bodies. Due to the drop-shaped quartz glass lens, it is possible to record a 360° surface image in just one workflow. This image is then transmitted to the eyepiece via achromatic lenses. A large number of illuminating fibers ensures optimal illumination, allowing for short exposure times when using image processing software. The panoramascope is used in quality control of brake cylinders, sleeves, connecting rods and pistons.
- Ø 6 mm and 11 mm
- Lengths: 80 mm to 400 mm
- Exchangeable panorama lens
- External focus ring
- Stainless steel design
- 360° all-round view

Top-line endoscopes are highly sophisticated endoscopy devices. This mature technology provides a high light yield and sharply defined objects. The classic Top-Line series is supplied as a complete set with 90° mirror tube and light source in a robust metal case. This endoscope is perfect for occasional mobile use. The Top-Line Pro version has a stepped focus ring and an optimized fiber-optic connection for the best possible light output. This makes the endoscopes ideally suited for use with a camera. The object is illuminated by an external light source. The Top-Line Pro endoscopes are optionally available with a temperature resistance of up to +300 °C.
- Ø 1.85 mm to 7.2 mm
- Lengths: 80 mm to 940 mm
- Focal range from 2 mm to ∞
- Series Top-Line as complete set in a case
- Top-Line Pro series with optimized fiber-optic connector and external focus ring
- Top-Line Pro optionally with temperature resistance up to +300 °C

The miniature endoscope ELTROTEC ME is ideally suited for the inspection of miniature components and channels in the field of microelectronics and precision engineering. In distinction to other miniature endoscopes with a gradient index lens, the ME can also be lightly bent without suffering damage. The image quality is comparable to that of all conventional lens systems.
- Ø 0.9 mm to 2.0 mm
- Lengths: 20 mm to 450 mm
- High quality quartz fibers
- Focusable from 1 mm to ∞
- Easily pliable - high break resistance provides robustness
- External focus ring for diopter adjustment
