Thank you very much for viewing. This is an Eschenbach professional precision inspection loupe, the "Precision Push-Out Loupe," 20x magnification. This loupe was used constantly for work, so it shows considerable signs of use. The paint is also quite worn. Please understand that this is a used item, and only purchase if you are comfortable with its condition. In photo 3, the Eschenbach loupe has a cloudy appearance in the center of the lens. The view is as shown in photo 12 when looking at the "ta" character on the paper in photo 10; the cloudy areas appear blurry. However, if you shift your viewing angle slightly and look at the cloudy area from an angle, it appears normal. Please consider this a junk item due to its years of use. ● Eschenbach ・Size: 27 x 43 x 19mm (Original Price: ¥22,000) ・Weight: Approximately 52g ・Specifications: Magnification: 20x, ・Lens Size: 17mmΦ ・Effective Lens Diameter: 12mmΦ ・Lens Type: Achromatic (Precision, Aberration-Free Color Correction) ・Original Price: Loupe for industrial precision inspection ● Contec Precision Double Mirror LP-30G (Original Price: ¥1,480) [Specifications]: Magnification (x): 8+10 Body Size: 31 x 16 x 40mm (when stored) Body Material: Body/ABS resin Lens/Acrylic resin Body Weight: 10g ● Contec Precision Triple Mirror LP-31G (Original Price: ¥1,860) [Specifications] ● Size: W42 x D27 x H61 (mm) (when stored) ● Weight: Approximately 35g ● Magnification: All lenses Φ27: Approximately 5x ● Main Materials: Lens: Acrylic resin, Body: ABS resin Other, unknown loupes, 2 types
