The Panasonic ET-C1W300 is a short throw zoom lens designed for Panasonic’s compatible projectors. It offers a 0.55–0.69:1 throw ratio, making it ideal for small to medium-sized rooms, allowing large images from relatively short distances, perfect for classrooms or meeting rooms.
Panasonic’s UED Glass Delivers Flawless Image Quality
Panasonic’s ET-C1W300 utilizes precision-ground Ultra Extra-low Dispersion (UED) glass lens elements to minimize light scattering, a common cause of flare and color blur. The lenses produce sharp, uniform visuals with realistic contrast and color performance.
Dramatically Improved Native Contrast Performance
Precision UED glass lens elements improve native contrast performance by as much as 16%2 over equivalent lenses in the DLE Series. Combined with the projector’s evolved Dynamic Contrast technology, this enhancement ensures that high-quality content is faithfully reproduced, drawing guests deeper into your experience.
Proprietary AR Coating for Exceptional Uniformity
Reflections from the lens surface and internal reflections can cause color irregularities and ghosting on the screen, degrading color uniformity. Employs a proprietary Anti-Reflection (AR) coating to prevent diffuse light reflection, depositing a thin film on the lens surface to reduce color irregularities and ghosting. The coating is particularly important for maintaining color uniformity with ultra-short-throw lenses: leverage Panasonic’s accumulated expertise in AR coating development, contributing to outstanding color uniformity.
Aspherical Lenses: Superior Imaging, Compact Design
The feature aspherical glass lens elements. Aspherical glass achieves the same effect as multiple lens elements, enabling high magnification power and reducing size and weight, particularly for larger lenses. Aspherical lens manufacturing demands extreme precision and expertise.
Panasonic answers with accumulated know-how, producing the large-diameter elements at a state-of-the-art facility in Yamagata, Japan, to ensure spectacular visuals in an easy-to-handle form factor.
Robust Lens Mounter Improves Stability
Projectors compatible with the C1 Series feature a revised lens mounter structure that strengthens vibration resistance, reducing the need for periodic focus adjustments. The labor-saving design also simplifies the installation of ultra-short-throw zoom lenses. Previously, an optional bracket was necessary for this lens type, which restricted the shifting range. The updated structure, complete with a hex-head screw kit, allows for bracket-free installation, saving time and resources.
Rugged Design Maintains Stable Image Quality
The C1 Series employs glass lens elements for durability in rental situations or for touring productions where lenses are frequently handled. Stable imaging is ensured by selecting heat-resistant materials less prone to aberrations resulting from temperature fluctuations. Proprietary simulation models temperature rises in the lens due to light exposure, allowing the best selection of materials to resist focus drift and reduce maintenance.
