Lensmeter capable of measuring near-infrared transmittance of eyeglass lens

A lensmeter comprising:

• a near-infrared ray transmittance measuring unit disposed at one end of a housing of the lensmeter, wherein the near-infrared ray transmittance measuring unit comprises:
• a light emitter including a near-infrared ray light source for irradiating a measured lens with a near-infrared ray;
• and
• a light receiver including a near-infrared ray sensor for measuring a near-infrared ray transmittance of the measured lens by detecting an intensity of the near-infrared ray passing through the measured lens;
• and
• a lensmeter unit, which comprises:
• a refractive power measuring light source for irradiating the measured lens disposed on a lens support with refractive power measurement light;
• and
• a refractive power detector that detects the refractive power measurement light whose optical path is changed based on a refractive power of the measured lens while passing through the measured lens disposed on the lens support and calculates optical characteristics of the measured lens from a light quantity distribution and an image formation position of the detected refractive power measurement light,
• wherein the near-infrared ray light source is a near-infrared ray LED that emits near-infrared rays having a wavelength of 760 nm to 1400 nm,
• wherein the refractive power detector is disposed below the lens support to support the lens support, the refractive power detector is integrally formed with the near-infrared ray transmittance measuring unit, and the refractive power detector and the near-infrared ray transmittance measuring unit have externally a single pillar shape, and
• wherein the refractive power measuring light source, the lens support, the refractive power detector, the near-infrared ray light source, and the near-infrared ray sensor are sequentially disposed in a vertical direction.
