This second-generation design uses a 2 mm thick, heat-resistant Eagle XG substrate with an anti-reflection coating effective from 350 to 1000 nm. The narrower 7µm slit is specifically included for high-precision applications, such as solar magnetic field measurement, giving spectroheliograph builders a critical optical component.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDual 7µm and 10µm Slits for High-Resolution Solar Work\u003c\/h3\u003e\n\u003cp\u003eThis GEN2 component incorporates two selectable slits on a single substrate, allowing you to switch between different resolutions without changing parts. The 10µm slit is excellent for general solar spectroscopy, while the finer 7µm slit enables more demanding, high-precision studies where greater spectral resolution is required. This narrower aperture is particularly effective for projects like measuring solar magnetic fields via the Zeeman effect.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e2mm Thick Eagle XG Substrate with 350-1000nm AR Coating\u003c\/h3\u003e\n\u003cp\u003eThe slit is fabricated on a specialized Eagle XG glass substrate, chosen for its thermal resistance and excellent transmission across a wide 350 to 1000 nm wavelength range. The 2 mm thickness makes the 12 x 8 mm blade robust and easy to handle. It also simplifies cleaning, as both sides can be safely wiped with absorbent cotton and water.
