Fashioned by hand – scrutinized by high-tech Coordinate Measuring Machines
The trial frame is one of the tools off the trade for every refraction professional. Subjective lens determination requires craftsmanship and manual skill. Your professional competence will be perfectly demonstrated with the new Universal Trial Frame UB 6. In the new product development of the UB 6 we put ergonomics, simple handling and optimal wearing comfort front and center.
Now, we proudly present the UB 6, made of the finest materials and featuring a new design. Many ideas and suggestions for improvements from our customers have been integrated in the new development: for example, the nose piece and its adjustment options have a fully new construction. Also new is the lens holder, with four slots in front and two behind.
The UB 6 is the new generation in OCULUS trial frames. Carefully crafted by hand with the highest attention to detail. All materials are optimally fine-tuned in their coordination, inspected, and measured with our 3D-coordinate measuring machine.
Trial lenses according to DIN EN ISO 9801 with a rim diameter of 38 mm (lens diameter 21 mm), such as the OCULUS trial lens “tl” (trial lens), are compatible with the Universal Trial Frame UB 3+, UB 4, UB 6 and Half-eye Trial Frames.
Universal Trial Frames UB 3/UB 3+, UB 4 and UB 6 are all suitable for any trial lens conforming to DIN EN ISO 9801 and having a rim diameter of 38 mm, such as a OCULUS “tl” trial lens.
However, our Universal Trial Frame UB 5 for small heads requires trial lenses of the “tls” line with a diameter of 28 mm. These also conform to DIN EN ISO 9801 and are available nowhere in the world but from OCULUS.
The UB 6 stands out for its trendy, modern design. The nose pad has been improved for better pressure distribution as well as in terms of adjustability. In addition, the front lens holder now offers four instead of the usual 3 slots, while the rear lens holder accommodates two lenses, as before.
Unique to the design of the UB 6 is the gradation of the scale for reading off the axis and base position, which is now in steps of 2.5°, allowing for greater reading accuracy. The operating elements now have an attractive conical design and are grooved to provide a better grip. Their somewhat harder material makes them more durable than those of earlier models.
The aluminium scales are absolutely abrasion-proof. Their high contrast makes for easy reading also in darkened rooms. The upward angled operating element for precise nose pad adjustment has been designed for easy use outside the test person’s field of view.
The flexible arms adapt to the shape of the ears and do not need to be adjusted.
All modifications and improvements were made in response to customer requests.
Yes, polarizing filters are always optionally available. Those for the UB 6 have a clip for easy mounting, while those for the UB 4 and UB 5 are to be directly slipped onto the trial frame.
Polarizing filters with a clip as well as those of the slip-on type are for lateral mounting and can be easily flipped to the side when not needed.
On the UB 3/UB 3+ the polarizing filter has a central mount and can be simply removed after use. All linear polarizing filters are reversible.
Circular polarizing filters are available both with a clip and in a slip-on version.
There are also circular polarizing filters available in trial lens size for use in a slot of the rear lens holder if one should be free.
If necessary we recommend cleaning your trial frames with a soft lint-free cloth only. To clean a heavily soiled trial frame you can use a damp cloth and a little household dishing-washing liquid. Never use alcohol, ether or similar solvents, let alone aggressive chlorinated, scouring or corrosive detergents.
For disinfection we recommend disinfection cloths such as Pursept®-A Xpress or Mikrozid® Sensitive Wipes from Schülke und Mayr GmbH. Please contact your OCULUS distributor so that they can order through OCULUS, or contact the source supplier directly: www.schuelke.com.
Universal Trial Frames UB 3+, UB 4, UB 5 and UB 6 are all delivered in a telescopic cardboard box.
This telescopic box has been designed so that it can be used for storing the trial frame in a drawer or together with the refraction unit. It is lined with hard-wearing PE foam to protect the trial frame.
The transparent sighting bar has one scale on its surface and one inside. Take your VD reading when you see the two scales in alignment. The millimetre values on the scale refer to the eye-side vertex of a trial lens located in the first slot of the rear lens holder (next to the trial frame body).
DIN EN ISO 1366 defines VD as follows: absolute value of the distance between the rear surface of the spectacle lens and the corneal apex measured along the line of sight, i.e. orthogonally to the plane of the rim.
The measurement should be taken with the reference lens in the first slot of the rear lens holder (next to the trial frame body).
