Lenses for Machine Vision
Sill Optics utilizes already since more than 40 years the benefit of telecentricity in optical projection systems. Especially for machine vision purposes these type of lenses offer big advantages over standard lenses. In this catalogue we have restructured our extraordinary variety of telecentric lenses into series with identical working distance and similar size. This allows the user a maximum flexibility with respect to camera size and magnification.
New in this catalogue are lenses for CCD cameras up to 1” and larger. Most of the telecentric lenses can be provided with integrated coaxial illumination. The user can choose between two options: A coupling port for a lightguide (S5LPLxxxx) or a already integrated LED ( S5LPLxxxx/LED). We offer LEDs in the R, G, B range or NIR. The LED types are the same as used in the supertelecentric condensers.
Image side telecentric lenses:
The image side telecentric lenses find their place in machine vision, if very high demands on the homogeneity of the sensor illumination are required. Also angular sensitive components between sensor and lens ( such as beamsplitters and filters) work only with low incoming angles of the light. We also recommend image side telecentric lenses in this case.
Double side telecentric lenses:
Double side telecentric lenses are commonly used with line sensors, but also with large matrix CCD sensors. These type of lenses provide nominally zero distortion and will be used in highly demanding measuring systems. Lenses for line sensors up to 160 mm have been realised already by Sill Optics.
Telecentric zoom lens:
Unique in its design is also the first real telecentric zoom lens by Sill Optics. The telecentricity is kept throughout the complete zoomrange from 0.5x..0.125x. In addition the distortion is always less than 1%.
CCD lenses:
A variety of standard imaging lenses for CCD Cameras with C- or F-Mount rounds up our program. For nearly any application from UV to IR a suitable lens can be found in this catalogue. The range cover from very low f-number macrolenses to long distance telelenses; wideangle - and zoomlenses complete the list.
The catalogue is structured in different resolution categories, to comply with the cost requirements of the customers. Special design for any application will be made in house along with prototyping and series production.
Super telecentric condensers:
To achieve most precise results with telecentric lenses, the use of telecentric illumination is essential. Our Super Telecentric Condensers collimate the light of a LED to a nearly perfectly parallel beam. The user can choose between different beamsizes from 30 mm up to 150 mm diameter and between various standard LED types in R, G, B and IR.
Brandnew is the aspheric version of the 30 mm condenser. This item achieves the same performance with only one precision asphere, which is matched to the angular distribution of the emitted light of the LED.
llumination components:
In addition to above condensers Sill Optics also offers LED-ringlights and LED-spotlights.
Accessories:
The accessory list for the lenses and illumination components lists coverglasses, prismadapters, lens holders, coaxial frontillumination adapters, and dimmers for the LEDs.
