Why settle for the ordinary when you can capture the extraordinary The Baader Venus U-Filter is a specialized tool designed for deep ultraviolet (UV) imaging, allowing photographers and astronomers to delve into a spectral region that is typically beyond reach. With its advanced coating technology, the Baader Venus Filter boasts an impressive transmission range from 300nm to 400nm, peaking at an 80% transmission rate. This high level of efficiency is critical for UV photography, where capturing fine detail and contrast is paramount.Crafted with a meticulous 20-layer dielectric coating stack atop a specially polished UG-11 substrate, the filter ensures complete rejection of light from 200nm to 1500nm, isolating the desired UV spectrum. This precision engineering surpasses the capabilities of traditional deep violet filters and simple interference filters, which often fall short in both transmission and rejection outside the crucial 320nm to 390nm range.The Baader Venus U-Filter is not just about transmission; it\'s about achieving the highest contrast and sharpest images possible. Its exceptional optical quality is consistent with Baader\'s renowned filter lineup, ensuring that your UV images are captured with the utmost clarity.Additionally, the filter\'s pass band includes the solar Calcium K-Line, presenting a unique opportunity for astrophotographers to document solar flare structures with remarkable detail.
