Photoresist materials are sensitive to UV and short-wavelength visible light — exposure during inspection can prematurely activate or degrade the resist. The U-25Y48 blocks these damaging wavelengths while transmitting the longer visible wavelengths needed for visual inspection and imaging, allowing operators to safely examine photoresist-coated wafers and substrates under the microscope without compromising the resist. The U-25 slider format provides a convenient, tool-free insertion into compatible Olympus microscope filter slider positions. Supplied in new condition as a genuine Olympus OEM component.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp style=\"font-family: 'Segoe UI Emoji', sans-serif;\" class=\"MsoNormal\"\u003e\u003cstrong\u003e🔎 Typical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"font-family: 'Segoe UI Emoji', sans-serif;\" class=\"MsoNormal\"\u003e• Photoresist inspection and process control in semiconductor and MEMS fabrication\u003cbr\u003e• Lithography wafer inspection requiring UV-blocking illumination\u003cbr\u003e• Safe visual observation of UV-sensitive substrates and coatings\u003cbr\u003e• Industrial microscopy in cleanroom and fab environments\u003cbr\u003e• Replacement of worn or missing U-25Y48 filter sliders on Olympus systems\u003c\/p\u003e\n\u003chr\u003e\n\u003cp style=\"font-family: 'Segoe UI Emoji', sans-serif;\" class=\"MsoNormal\"\u003e\u003cstrong\u003e📊 Key Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\" style=\"border-collapse: collapse; font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f2f2f2;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"background: #f2f2f2;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eOlympus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eU-25Y48 - 9-U738\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilter Type\u003c\/td\u003e\n\u003ctd\u003eYellow Longpass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCutoff Wavelength\u003c\/td\u003e\n\u003ctd\u003e480 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFormat\u003c\/td\u003e\n\u003ctd\u003eU-25 Slider\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003ePhotoresist Observation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003cp style=\"font-family: 'Segoe UI Emoji', sans-serif;\" class=\"MsoNormal\"\u003eUniversity and institutional customers are welcome to submit purchase orders.
