BAUSCH

BAUSCH, historically known as Bausch & Lomb, is an American optical company with roots dating to 1853, when John Jacob Bausch and Henry Lomb established a partnership in Rochester, New York. The company built its early reputation on eyewear, optical instruments, and precision lenses, and its magnifier and loupe lines have been used for decades in watchmaking, jewelry, electronics, and inspection-intensive trades. The products supplied by 3G Electric under the BAUSCH handle are concentrated in two families: watchmakers' loupes and magnifiers. The watchmakers' loupe range includes 4X, 5X, 7X, and 10X models with 25.40 mm lens diameters, diopter ratings of 16D, 20D, 28D, and 40D, and focal distances from 1.1 in to 2.5 in. These are single-lens loupes intended for close-up inspection and assembly of small components. The magnifier range covers folding pocket magnifiers, illuminated Coddington magnifiers, and Hastings Triplet magnifiers. Representative specifications include a 4X to 9X folding pocket magnifier with a 23 mm lens diameter and dual focal distances of 1.1 in and 2.5 in; a 10X illuminated Coddington with a 40D diopter, 19.8 mm lens diameter, and 2.5 cm focal distance; and a 20X Hastings Triplet with an 80D lens, 8.3 mm lens diameter, and 0.5 in focal distance. Hastings Triplet construction uses three lens elements to reduce chromatic aberration, which is relevant where color fidelity affects inspection judgments. Across the line, the common thread is optical specification rather than electrical or mechanical ratings: magnification, diopter, lens diameter, and focal distance are the parameters a buyer needs to match the tool to the task. 3G Electric supplies these BAUSCH optical tools as part of its industrial-equipment catalog, with multiple SKUs available and logistics support for global delivery. For procurement and maintenance teams, the practical selection criteria are working distance, field of view, and whether illumination or portability is required. A loupe with a 1.1 in focal distance suits tasks where the eye must be close to the work, while a 2.5 in focal distance allows more clearance for tools or hands. Lens diameter affects the usable viewing area, and higher magnification generally means a smaller lens and shorter working distance. The BAUSCH range covers these trade-offs across discrete SKUs, so a single specification can be selected per workstation rather than compromising with a general-purpose tool.

Frequently asked questions

Common questions about BAUSCH from 3G Electric.

What magnification and focal distance options are available in the BAUSCH watchmakers' loupe range?

The BAUSCH watchmakers' loupe range supplied by 3G Electric includes 4X, 5X, 7X, and 10X models. Diopter ratings are 16D, 20D, 28D, and 40D respectively. All four models use a 25.40 mm lens diameter. Focal distances are 2.5 in for the 4X, 5.1 cm for the 5X, 1.4 in for the 7X, and 1.1 in for the 10X. Higher magnification corresponds to shorter working distance and higher diopter. Selection depends on the clearance needed between the eye and the workpiece and the level of detail to be resolved.

What is the difference between the BAUSCH Hastings Triplet magnifier and the Coddington magnifier?

The BAUSCH Hastings Triplet magnifier uses a three-element lens design, which is intended to reduce chromatic aberration and provide a clearer image across the field of view. A representative 20X Hastings Triplet has an 80D lens, 8.3 mm lens diameter, and 0.5 in focal distance. The BAUSCH Illuminated Coddington magnifier is a single-lens design with built-in illumination; a representative 10X model has a 40D diopter, 19.8 mm lens diameter, and 2.5 cm focal distance. The Coddington is suited where ambient light is insufficient, while the Hastings Triplet is suited where color and edge definition matter.

Can the BAUSCH folding pocket magnifier be used for field inspection?

The BAUSCH folding pocket magnifier is designed for portability. It offers 4X to 9X magnification with a 23 mm lens diameter and focal distances of 1.1 in and 2.5 in. The folding form factor protects the lens when not in use and allows the unit to be carried in a pocket or tool case. It is suitable for field settings where a bench magnifier or loupe is not practical. For tasks requiring higher magnification or illumination, the Hastings Triplet or Illuminated Coddington models are more appropriate.

How do I select the correct BAUSCH loupe for electronics assembly or watchmaking?

Match the focal distance to the working clearance and the magnification to the feature size. For watchmaking and jewelry work, the 5X and 7X watchmakers' loupes with 5.1 cm and 1.4 in focal distances are commonly used for component placement and inspection. For electronics assembly, the 10X loupe with a 1.1 in focal distance provides higher magnification where the eye can be close to the board. If illumination is needed, the 10X Illuminated Coddington is an alternative. Lens diameter determines the viewing area; the 25.40 mm loupes offer a larger field than the 15.80 mm Hastings Triplet.

What diopter ratings are available across the BAUSCH magnifier and loupe line?

Diopter ratings in the BAUSCH line supplied by 3G Electric range from 16D to 80D. The watchmakers' loupes cover 16D, 20D, 28D, and 40D. The 10X Hastings Triplet loupe is 40D. The 10X Illuminated Coddington is 40D. The 20X Hastings Triplet magnifier is 80D. Diopter is a measure of lens power and is inversely related to focal distance: higher diopter values produce shorter focal distances and greater magnification. Buyers should confirm the diopter and focal distance against the intended working distance before ordering.

Does 3G Electric supply BAUSCH optical tools outside Singapore?

Yes. 3G Electric is a Singapore-headquartered industrial-equipment distributor with global reach. BAUSCH loupes and magnifiers are supplied as part of the catalog with multiple SKUs available and logistics support for international delivery.
