宇隆 - 您的滤光片合作伙伴
昆明宇隆光电技术有限公司坐落于中国历史上四大光学基地之一——云南昆明，创立于1999年。经过21年的发展，宇隆形成了以天文滤镜、荧光滤光片和带通滤光片为主，UV镜、紫外/红外滤光片、分光镜、二向色镜、反射镜、窗口保护片以及其他光学滤光片为辅的产品线。目前拥有员工近60人，厂房面积超过2000㎡。
Optolong是我们的商标。我们既有自己的品牌产品——天文滤镜与荧光滤光片，同时也提供滤光片的设计、定制加工、打样与量产的整体解决方案。
宇隆是国内一家拥有自己的天文品牌的滤镜厂商。至今，Optolong®天文滤镜在全世界30多个国家有经销商，客户遍及世界各地。我们的天文滤镜曾登上美国《Astronomy》杂志。产品L-Pro被广大天文爱好者亲切地称为“老婆滤镜”，其他产品UHC, H-Beta, O-III, H-Alpha, SII, LRGB, Night Sky H-Alpha等都深受专业摄影师及天文爱好者的喜爱。
宇隆的另一个主产品是荧光滤光片。目前国内荧光滤光片的生产技术还未成熟，荧光成像普遍存在偏色与截止深度不够的问题，荧光滤光片套装更是少有。宇隆是国内一家生产荧光滤光片套装与FISH滤光片套装的厂商。我们荧光的主要产品有FISH滤光片,单带通荧光套装DAPI, FITC, TRITC, Texas Red, GFP, CFP, Cy5等。我们生产的荧光滤光片背景深谙、颜色纯正、对比鲜明，得到了大量客户的正面反馈，为荧光设备生产商、大学和研究机构提供了有利帮助。
宇隆拥有一批高素质的具有丰富实践经验的高级科研技术人员和熟练光学工人，具备自行设计、研究各类光学薄膜的能力，可根据客户的要求，开发和批量生产高难度光学滤光片。我们生产的光学滤光片经久耐用，通过了ISO9001、RoHS、SGS、CTI等多项认证，广泛用于机器视觉、医疗领域、生命科学、工业检测与激光光电等领域。
21年来，宇隆精耕细作, 坚持小而美的理念，在滤光片行业不断做深做精。我们以优质的产品，合理的价格和及时交货，为你创造更多价值，成为您可信赖的光学滤光片合作伙伴！
离子束辅助沉积真空镀膜
在镀膜工艺上，宇隆可提供离子辅助镀膜和热蒸发镀膜。
离子辅助镀膜技术能够设计和生产多种复杂的、需要多层镀膜的滤光片。我司主要的离子辅助镀膜设备是光驰OTFC-1300镀膜机。它可以使截止深度达到OD7的同时，使透过率维持在96%，且镀膜后的滤光片光谱性质稳定，经久耐用，量产的时候也能保持一致的光谱性质。
使用热蒸发镀膜的主要产品为增透膜（AR膜）和窗口保护片。
测试
激光干涉仪——检测基片面形的平整度，透过波前差及平行度，分辨率为 λ/20。
分光光度计——测量范围190nm-3200nm，可测量透过率及反射率，分辨率为0.001%，采样间隔0.01nm。
光学测角比较仪——测量光学平板的平行差，参照标准角规进行角度比较测量，两个平面间的垂直度测量。
平行光管——综合评价、检验光学系统和产品象质、分辨率。
性能——可靠、精确、可重复
（1）40°- 80°的环境下对温度变化不敏感；
（2）滤光片的性能稳定，可以维持多年；
（3）产品严格遵循MIL-C-48497A美军标标准；
（4）波长波动在+/-1nm；
（5）不管产品是单批次生产还是多批次生产，滤光片的光学性能和表现几乎相同。
