{"product_id":"window-film-tint-meter-ls161","title":"Window Film Tint Meter LS161 with 940nm IR Channel","description":"\u003cp\u003eThe Linshang LS161 window film tint meter compares visible light transmission with UV and infrared rejection on thin film samples. Its 940nm infrared channel helps distinguish how films respond at that test wavelength. A compact gray body and color display make it practical for sample demonstrations, receiving checks and film quality-control work.\u003c\/p\u003e\u003ch3\u003eThree optical readings on one display\u003c\/h3\u003e\u003cp\u003eInsert a film less than 0.8mm thick into the slot to see the result. The visible channel follows the CIE photopic response across 380–760nm, while the ultraviolet channel uses a 365nm peak wavelength. Select visible transmission alone, three transmission readings, or visible transmission with UV and IR rejection.\u003c\/p\u003e\u003cp\u003eThe infrared result is specific to the 940nm channel. When comparing film samples, use the same instrument and display mode so each reading describes the same optical quantity. The slot is intended for thin film samples, with the material covering the measurement area.\u003c\/p\u003e\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0273\/2133\/5851\/files\/window-film-tint-meter-ls161-rotating-display.jpg?v=1793767266\" alt=\"LS161 display rotating for readings in either orientation\" width=\"990\" height=\"616\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003cfigcaption\u003eLS161 display rotating for readings in either orientation\u003c\/figcaption\u003e\u003c\/figure\u003e\u003ch3\u003eRead and retain film results\u003c\/h3\u003e\u003cp\u003eThe 240 x 240 TFT screen uses colored progress bars to make the selected readings easy to scan.
