### Description

<p>The Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH), intends to award a firm-fixed-price purchase order to Block Engineering LLC on a sole-source basis for a Quantum Cascade Laser and associated detector and thermocooler.</p>

<p>The equipment will be used in support of NIOSH research to develop a portable real-time monitor for respirable crystalline silica. The quantum cascade laser and detector will be used with aerosol sampling equipment to measure infrared absorption characteristics associated with respirable crystalline silica.</p>

<p>Market research identified Block Engineering LLC as the only source currently known to provide a 12.5 &micro;m wavelength tunable laser meeting the Government&#39;s required size, weight, and performance requirements. The size and weight requirements are necessary because the equipment will be incorporated into a portable field instrument.</p>

<p>However, all responsible sources that believe they can meet the Government&#39;s requirements may submit a quotation or capability information for consideration by the Government by the response date identified in this notice.</p>

<p>Responses shall include sufficient technical information to demonstrate the source&#39;s ability to provide equipment meeting the requirements of the solicitation.</p>
