Manual Lensmeter Lensometer Focimeter

The Manual Lensmeter / Lensometer / Focimeter manufactured by Glass Agencies under the brand EROSE is an optical measuring instrument used for checking the optical power and alignment of spectacle lenses. This instrument helps determine the spherical and cylindrical power of lenses along with the axis orientation and prism measurement. It is widely used in optical shops, eye clinics, hospitals, and ophthalmic teaching institutions where verification of spectacle lenses is required. The instrument works through an optical viewing system that allows the user to observe lens power through an eyepiece. By placing the spectacle lens on the lens holder and adjusting the focusing mechanism, the examiner can read the lens power values from the measurement scale. The focusing drum helps adjust the optical system so that the target pattern inside the instrument becomes clearly visible, allowing accurate reading of lens characteristics. The lens holding platform allows secure placement of spectacle lenses during the measurement process. A lens holder clamp gently secures the lens in position so that it remains stable while readings are taken. The axis wheel allows rotation of cylindrical lenses to determine their axis alignment during measurement. The instrument also includes a scale system that helps determine prism values when required. The optical pathway inside the instrument allows light to pass through the lens being examined and project a target pattern that changes according to the lens power. By adjusting the focusing system, the examiner can determine the exact optical strength of the lens. This method helps confirm whether the lens matches the required prescription before it is fitted into spectacle frames. The compact structure allows the instrument to be placed conveniently on optical worktables or dispensing counters. Its stable base allows smooth operation during repeated lens measurement tasks performed throughout the day in optical environments. The EROSE Manual Lensmeter / Lensometer / Focimeter, produced by Glass Agencies, supports systematic verification of spectacle lenses by helping measure optical power and alignment.
