The light of truth hidden within black. Distortion-free doublet lens. The ultimate Linen Tester trusted by professionals: the “DS25.”
In environments requiring rigorous inspection, lens distortion and stray reflections can lead to misjudgment. The Linen Tester DS25 loupe is designed to eliminate these sources of error.
Its doublet lens ensures a flat, distortion-free image across the entire field of view, while its full-black body minimizes unwanted light interference. A precision measuring instrument engineered to reveal the most accurate results.
Vixen Magnifier Linen Tester Loupe DS25 Description
-
A 2two-element (doublet) lens design that minimizes aberrations.
● Distortion Correction
By combining two lens elements, distortion in the peripheral field of view―common in single-element lenses―is significantly reduced.
● Reduction of Chromatic Aberration
Color fringing is minimized, delivering sharp, well-defined image outlines. A clear field of view is maintained from the center to the edge of the lens, as if your naked eye were brought closer. -
A full-black finish that maximizes contrast.
By unifying the entire design―from the lens frame to the base and even the interior surfaces―in a black finish, visibility is enhanced.
External reflections and internal stray light are effectively suppressed. By directing only the light from the object to the eye, it delivers exceptional contrast and a highly immersive viewing experience. -
A "6x magnification, 25mm" lens designed for ultimate practicality.
●Iptimal Balance
By setting the magnification to 6×―slightly lower than the standard DS20 (7×)―a greater depth of field is achieved.
●Brightness and Resolution
The combination of a generous 25 mm aperture and high-transmittance lenses provides a bright field of view that reduces eye strain. These specifications are designed for professionals who need to make critical judgments over extended periods. -
Built-in scale for quantifying details
Measurable Loupe: The base is engraved with a high-precision 1 mm scale, allowing instant measurement of magnified objects and dot counts (halftone screens or weave patterns) within a defined area.
-
Foldable lens frame
●Compact Storage
When folded into three, it becomes completely flat with a thickness of just 13 mm. It can be easily stored in small spaces such as pockets or drawers.
●Robust Metal Body
Features a robust metal frame designed to withstand frequent opening and closing as well as heavy field use. -
Use cases
●Business Use
①Verification of fine art prints. Chromatic aberration is suppressed, making it ideal for final color judgment and checking the shape of extremely small dots.
②Quality control. To avoid overlooking even slight cracks or foreign matter. The black body prevents glare and reduces inspection errors.
③Appraisal. When appraising and evaluating works of art, the distortion-free view of the DS25 is ideal.
●Hobbies/Everyday Use
④For stamp collecting. Ideal for checking the number of perforations (serrations) on stamps and minute printing misalignments.
⑤For carefully observing plant veins and insect wing patterns. Its design allows for easy observation, making it suitable for children's observations.
⑥For photo verification. For checking positive film and contact prints. Highly effective for checking flat details.
