The entrance slit controls the width and alignment of light entering the spectrometer, defining the initial beam characteristics. It determines spectral resolution and light throughput, impacting sensitivity and accuracy.
The blades can be made of stainless steel, tungsten, or quartz. Stainless steel 304 is commonly used, conforming to ASTM A240, offering corrosion resistance and durability.
The slit width is mechanically controlled via a micrometer screw or motorized actuator. The adjustment accuracy is ±0.001 mm, and repeatability is ±0.002 mm.
The operating temperature range is -20 to 60 °C, storage temperature -40 to 85 °C, and relative humidity up to 95% non-condensing. Condensation may affect performance.
