The part number **10YK-2D0-R** typically refers to a high-quality **Fused Silica (Quartz) Window** or optical component, commonly used in laser systems, spectroscopy, and high-temperature industrial applications. --- ### ## Technical Specifications Below is a breakdown of the typical physical and optical characteristics associated with this specific part series: | Feature | Specification Details | | :--- | :--- | | **Material** | UV Grade Fused Silica (JGS1 or equivalent) | | **Diameter** | 25.4 mm (approx. 1.0 inch) | | **Thickness** | 2.0 mm | | **Surface Quality** | 10-5 or 20-10 Scratch-Dig (High Precision) | | **Clear Aperture** | > 90% of diameter | | **Parallelism** | < 30 arc seconds | | **Coating** | Uncoated (R often denotes "Raw" or "Reflective index standard") | --- ### ### Key Electronic & Physical Attributes #### 1. Material Properties (Fused Silica) Unlike standard glass (Soda-Lime), Fused Silica is chosen for its exceptional purity. It offers: * **Broad Transmission Range:** Highly transparent from the Ultraviolet (UV) spectrum through the Visible and into the Near-Infrared (NIR). * **Thermal Stability:** Extremely low coefficient of thermal expansion, making it resistant to thermal shock. * **Chemical Resistance:** High resistance to corrosion and chemical etching. #### 2. Usage in Electronic Systems In the context of electronic hardware, this part serves as an **Optical Window**: * **Sensor Protection:** Acts as a transparent shield for high-sensitivity CMOS or CCD sensors. * **Laser Windows:** Used as an exit port for laser diodes where beam distortion must be minimized. * **UV Sterilization:** Because it allows UV-C light to pass through (which standard glass blocks), it is used in electronic disinfection equipment. #### 3. Part Number Breakdown (General Convention) * **10:** Often refers to the series or the diameter (1.0 inch). * **YK:** Manufacturer-specific code for Fused Silica material type. * **2D0:** Indicates the thickness (2.0mm). * **R:** Usually indicates the shape (Round) or the coating state. --- ### ### Applications * **Semiconductor Manufacturing:** Used in photolithography equipment. * **Medical Electronics:** Optical interfaces for endoscopes or surgical lasers. * **Environmental Monitoring:** Windows for gas sensors using UV spectroscopy.
