EQ-99X-FC LDLS®

High-Brightness, Broadband Light Source with Fiber-Coupled Output

EQ99XFC_no-background2

Enhanced DUV Performance

The EQ-99X-FC LDLS is a high radiance, broadband light source with integrated collection optics built for systems with fiber connections.

The EQ-99X-FC’s high-performance ellipsoidal collector maintains the ultra-high brightness and spatial stability across the broad spectrum, from 190 nm to 2500 nm, and efficiently couples into small diameter optical fibers.

Proprietary Fiber-Protection Technology™ enhances DUV performance and significantly extends fiber life by reducing the effects of solarization. Utilizing a patented laser-driven bulb technology* and ultra-clean construction, the EQ-99X-FC is ideal for applications requiring ultra-long lamp life and advanced illumination.

Fiber Optic Cable Assemblies

Our proprietary fiber optic cable assemblies must be used with the EQ-99X-FC LDLS. There are two types of fibers available: UV-Vis Solarization Resistant (UV) and Broadband (BB). Both the UV and BB fibers transmit from 190 nm – 2500 nm. However, the UV fibers are constructed using silica with a high concentration of hydroxyl groups (OH) and are engineered to withstand ultraviolet solarization. The UV fibers are ideal for applications benefiting from enhanced radiance from 190 nm – 350 nm and the BB fibers are preferable for applications that benefit from enhanced radiance from 350 nm – 2500 nm. For details about the different options available, please refer to our Fiber Optic Cable Data Sheet.

Frequently Asked Questions

 Is there a fiber-coupled version of the LDLS?

 Yes, the EQ-99X-FC is a fiber-coupled version of the EQ-99X free-space LDLS. Energetiq sells two types of fibers for use with the EQ-99X-FC LDLS. They are UV-Vis Solarization Resistant (UV) and Broadband (BB). 

 What is the difference between UV-Vis Solarization Resistant (UV) and Broadband (BB) fibers?

Both the UV-Vis and Broadband fibers transmit from 190 nm to 2500 nm. However, the UV-Vis fibers are constructed using high OH material and are engineered to withstand ultraviolet solarization. They provide higher output from 190 nm to 900 nm when compared to Broadband fibers of comparable core size.

The UV fibers are ideal for applications benefiting from enhanced radiance from 190 nm – 350 nm and the BB fibers are preferable for applications that benefit from enhanced radiance from 350 nm to 2500 nm.

 What is the fiber output termination?

All fibers connect to the lamphead via FC connection and are available with either SMA or FC output termination. The user can select the termination for the output end of the fiber according to their application requirements.

 How do I select the correct fiber for my application?

First you must select either the UV-Vis or Broadband fiber type as described above. For each fiber type there are multiple core size options. Every fiber is available at 1 or 2 meter of length and are available with either SMA or FC output termination. Reference the Fiber Optic Cable Assemblies data sheet for additional information.

For instance, the UVFIBERX-115-1M-FC-SMA is a UV-Vis fiber with a 115 μm core size, 1 meter length and SMA output termination.

 Is it possible to use non-Energetiq fibers to couple the EQ-99X-FC LDLS?

Our proprietary fibers must be used with the EQ-99X-FC. Using off-the-shelf, commercially available fibers can cause damage to the lamp head and are not approved for use with the LDLS.

 What is the numerical aperture of the fibers? Is the fiber PC or APC? Is the fiber narrow key or wide key?

All EQ-99X-FC fibers have a numerical aperture (NA) of 0.22, and are PC type with narrow key.

Is there a limit on the output fiber length from the lamp head to the application?

For both the UV resistance and broadband fibers, Energetiq offers one- and two-meter-long fibers. Since even the best optical fibers absorb light in the deep UV, it is recommended to use the shortest fiber length possible to maximize the potential of the LDLS. EQ is able to offer custom fiber lengths upon request.
