Manufacturer Optical Glass 349nm 350nm 365nm Camera UV Filter narrow bandpass filter
New technical advantages The near-ultraviolet narrow-band filter can achieve a half-width of 10 nm and a transmittance of more than 15%.
High Index Ball Lens
Ball lenses feature short back focal lengths to minimize the distance needed from the ball Lens to the optical fiber. Ball lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Half-Ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy, microscopy, optical pick-up devices,and laser measurement systems
Aspheric Lenses Condenser Lenses
For Precision Polished Aspheric Lenses Worldhawk offers precision polished aspheric lenses, with and without anti-reflection (AR) coatings. These lenses are available in larger sizes, provide better surface quality, and maintain the M squared values of the input beam better than their molded aspheric lens counterparts. Aspheric Condenser Lenses Worldhawk' Aspheric Condenser Lenses offer larger apertures, higher NA, and lower f/# ratios than spherical lenses. Therefore, these lenses are ideal for high-efficiency illumination applications or collimating light from a lamp, LED, or similar light source.

IR CUT Bandpass Filters
Our IR CUT filters have a steep transition between the region of transmission and reflection, with deep blocking and typical transmission > 90% for passband.
1 We can provide you with high precision powell lenses. 2 It has better line straightness for the laser line. 3 Power Uniformity can be controlled to 25%. 4 All the powell lenses are machined and not by handmade, so better product consistency.
