Resin lens for head-mounted display |
| abstract |
The present invention aims to provide a resin lens for a head-mounted display that can obtain a clear image even in an optical system using polarized light. The lens for a head-mounted display is characterized in that the average value of the absolute values of the phase differences within the effective diameter is 5nm or less, and the concentration-intensity of an ethanol solution using fluorescein is determined from the fluorescence intensity at a wavelength of 530nm when a 2.0 mass% solution obtained by dissolving chloroform is measured at an excitation wavelength of 436nmThe content of the fluorescent substance determined by the formula of degree conversion is 0.1 × 10 ‑9 ～4.0×10 ‑9 mol/L。 |
