30um Thick LiTaO3 Thin Film Pyroelectric Elegance Redefined 3 Inch 4 Inch
3 Inch 4 Inch 30um Thick LiTaO3 Thin Film: Pyroelectric Elegance Redefined
Delve into the elegance of LiTaO3 thin film and its pyroelectric effect, where sensitivity meets sophistication. Our ultra-thin LiTaO3 wafers, boasting a wafer-level thickness of 20um and a diameter extending up to 4 inches, are the epitome of this refined technology. As temperature fluctuations induce the pyroelectric effect in LiTaO3, these wafers become pivotal in applications such as flame detection and spectroscopy. The thinness of our wafers amplifies the responsiveness, making LiTaO3 a material of choice for those seeking precision in their technological innovations.
