COT-L800 Hartmann auto lensmeter with extended ±35 D sphere range — the high-Rx-specialist lensmeter for post-cataract and refractive-surgery practices.
Clinical overview
The OpticsMED COT-L800 is the extended-range Hartmann auto lensmeter — supports sphere measurements up to ±35 D, well beyond the standard ±25 D range. The result is the verification lensmeter for clinics that routinely handle post-cataract pseudophakic Rx (sometimes ±30+ D), post-refractive-surgery enhancements and high-myopia stock that exceeds normal ranges.
| Sphere | 0 to ±35 m⁻¹ |
|---|---|
| Sphere accuracy | ±0.06 to ±0.25 (range-dependent) |
| Cylinder | 0 to ±10 m⁻¹ |
| Axis | 0–180° (1° step) |
| Prism accuracy | 0.1–0.2 Δ (range-dependent) |
| Power | 110–110V/240V, 50–60 Hz |
Post-cataract surgery clinics, refractive-surgery practices, high-myopia specialty optometry and any verification bench handling Rx beyond the standard ±25 D range. The extended-range coverage is the differentiator.

Been putting it through daily use in the clinic and the components fit and function exactly as described. It's held up well to consistent daily use. Solid purchase overall.
Nina Wilson, Optometric TechnicianVerified buyerJan 13, 2025
Ordered this to replace an ageing unit and so far it feels solid and properly engineered. The value at this price point is hard to beat. Happy to recommend it to colleagues.

The LM-260 is a desktop auto lensmeter for verifying single-vision, bifocal and progressive lens prescriptions, with sphere, cylinder, axis, prism and addition measurements as part of the standard workflow. Prism measurement on the dispensing bench is helpful for verifying made-to-order glasses with prescribed prism corrections. The desktop format suits optical dispensaries, optometry practices and lens-finishing labs. A solid everyday verification tool for mid-range dispensing setups.
The CCQ-1100 is an automatic lensmeter built around a Hartmann sensor with 165 sampling points and a high-speed dual-core processor. It performs automatic recognition of single-vision, multifocal, and progressive lenses, and includes blue light measurement and UV protection display functions. It is intended for optical labs, dispensing opticians, and clinics that need a daily lensmeter for prescription verification. It is supplied as a desktop unit for the dispensing or finishing bench.
The L-5000B is a desktop auto lensmeter for verifying single-vision, bifocal and progressive lens prescriptions on the dispensing bench. It covers the standard spectacle-lens range optical dispensaries need for everyday quality control and incoming-lens checks. The desktop format and straightforward operation suit busy optical retail counters and lens-finishing labs. A practical core instrument for any optical dispensary.
The HV-100 is an auto lensmeter built around Hartmann wavefront analysis for verifying single-vision, bifocal and progressive lens prescriptions. Wavefront-based reading helps the device handle progressive add zones and complex lens designs that classic green-light lensmeters can find harder to map. Aimed at optical dispensaries, optometry practices and lens-finishing labs that need a reliable verification step. A practical core tool for any modern optical retail or lab workflow.
The L890 is an auto lensmeter built around a Hartmann array sensor with a green LED light source and a 7-inch color touch screen for everyday lens verification. It reports sphere, cylinder, axis, PD and PH, supports colored lenses down to 10% transmittance and reads down to ±0.12 D minimum lens power. Optional PD/UV measurement and a thermal printer let the device grow with the dispensary's workflow. Aimed at optical retail, optometry practices and finishing labs looking for a flexible mid-range lensmeter.
The LM-900 is a desktop auto lensmeter using a Hartmann sensor with 108 measurement points and a 0.1-second reading time, aimed at busy dispensing benches that need quick lens checks. Measurement ranges cover sphere up to ±25 D, cylinder up to ±9.99 D, axis across 0-180 degrees and reading addition up to 9.99 D, with prism up to 15Δ. A 3.5-inch color LCD touch display keeps the workflow simple, and the 3 kg form factor stays out of the way on the bench. This variant ships without a printer and without binocular PD, keeping the unit focused on core verification.
The HV-300 is an auto lensmeter that measures single-vision, bifocal, progressive and contact lens powers in one device, extending the standard spectacle-lens workflow into contact-lens verification. Contact-lens measurement makes it useful for practices that fit and replace soft and rigid lenses alongside spectacle dispensing. The unit is aimed at optical dispensaries, optometry practices and contact-lens fitting rooms. A practical step up from spectacle-only lensmeters for clinics with mixed dispensing workflows.
