所有ULTRA系列二向色和多色滤光片均可定制为超平面滤光片，以最大限度地减少失真并保持成像和基于激光的荧光系统的最佳性能。将超平面二色性纳入这些系统将产生清晰的图像，最小的焦点位移和准确量化目标分子。当在632.8nm处测量时，可以定制超平坦二向色滤光片，其具有优于0.1波长PV /英寸的平坦度。
创新的薄膜工艺使产品质量一致性
图4. ULTRA系列滤光片的波长控制，传输和截至在几种不同的涂层运行中具有高度可重复性。
Alluxa薄膜滤光片和介质反射镜均采用我们的SIRRUS™离子束沉积硬镀膜技术，这使我们能够在多个不同的涂层运行中可靠地重复生产相同的高性能薄膜带通滤波器，这意味着您的所有系统性能始终如一。
