Edmond Scientific Company (Edmond), of Chantilly, Virginia protests the decision by the Department of the Army, Medical Research Acquisition Activity, not to set aside for small businesses a task order proposal request (TOPR) No. TOPR 14MC22318, issued under a multiple-award, indefinite-delivery/indefinite-quantity (ID/IQ) contract for a variety of business-process and other support services. The protester argues that the Army's decision not to reserve this task order for small business participation lacked a reasonable basis, was an abuse of discretion, and violated Federal Acquisition Regulation (FAR) 19.502-2(b), the so-called "Rule of Two."

[1] The facts alleged and arguments raised by this protest are virtually identical to those denied by our Office in Edmond Scientific Co., B-410179, B-410179.2, Nov. 12, 2014, 2014 CPD ¶ 336.
DOCUMENT FOR PUBLIC RELEASE The decision issued on the date below was subject to a GAO Protective Order. This redacted version has been approved for public release.

At issue here is whether the value of the task order will be above or below the $10 million threshold for our jurisdiction. The TOPR, as amended, provides for evaluation of price and non-price factors, and states that the evaluated total price of a proposal will be “the total of all the priced line items for the base year and all options.” Agency Report (AR), Tab 14, TOPR amend. 3, at 21, 22. The independent government estimate (IGE), which the Army calculated by including estimates for the base year, three one-year options, and one ten-day transition option, values the order at approximately $[deleted] million. AR, Tab 3, IGE, at 3.
Edmond argues that the IGE does not accurately represent the value of the order, because the TOPR also included FAR clause 52.217-8, which reserves for the government a six-month option to extend services. Comments at 8. In this regard, the protester relies on the statement in the TOPR that the total evaluated price would include “all option periods,” and maintains that “all option periods” must include the option to extend. Comments at 9; AR, Tab 14, TOPR amend. 3, at 21, 22. Edmond contends that including the value of the option to extend in the IGE--which in the protester’s view, should be valued at half the value of the third option year--would increase the task order’s value above the $10 million threshold. Comments at 9, 10.

For both the Galilean and Keplerian configuration the output beam divergence can be calculated by the beam divergence of the input beam and the diameters of both output and input beams. In both cases, the ratio of input beam divergence to output beam divergence is equal to the ratio of output beam diameter to input beam diameter. This ratio is equal to the magnifying power of the beam expander system.
In sum, the protester has not shown the agency’s IGE to be inconsistent with the terms of the TOPR or an inaccurate measure of the total value of the task order. Since that value is below $10 million, our Office does not have jurisdiction to consider the protest.[3]
[2] The facts here are distinguishable from our decision in Serco Inc., supra, where the solicitation expressly provided for the evaluation of the value of the option to extend services. See also Major Contracting Servs., Inc., B-401472, Sept. 14, 2009, 2009 CPD ¶ 170 at 4 (where option to extend is not evaluated as part of the initial competition, contract extension is effectively a new procurement); Id. at 6 (rejecting argument that evaluating base year and option year prices is equivalent to evaluating price for option to extend).
GAO lacks jurisdiction to hear protest of task order solicitation where independent government estimate of task order’s value, exclusive of the value of option to extend services, is below $10 million and solicitation does not provide for evaluation of option to extend services.
Beam expanders are used whenever the diameter of a collimated beam must be increased. They can also be used to change the focus spot size for a focusing lens, or to keep a beam collimated in optical systems that have a long beam path.
A Keplerian telescope consists of two plano-convex convergent lenses placed so that the distance between the lenses is equal to the sum of their focal length. These simple beam expanders have high expansion ratios. Because the two lenses have positive focal lengths the input beam will focus at a point between the two lenses, enabling spatial filtering. However, that same property makes Keplerian beam expanders problematic for high power laser applications, as the resulting energy density and heat at the focal point can deflect light and lead to wavefront errors.

Beam expanders that consist of two lenses are known as telescopic beam expanders. These transmissive beam expanders can be divided into two primary types: Keplerian beam expanders and Galilean beam expanders.

Beam expanders increase the diameter of beams of collimated light and simultaneously decrease beam divergence. At Avantier we produce custom beam expanders for laser applications as well as remote sensing and interferometry.
Protests filed with our Office in connection with the issuance or proposed issuance of a task or delivery order under a multiple-award contract are not authorized except where the order is valued over $10 million, or where the protester can show that the order increases the scope, period, or maximum value of the contract under which the order is issued. 10 U.S.C. § 2304c(e) (2012); see e.g., e-Management Consultants, Inc.; Centech Group, Inc., B-400585.2, B-400585.3, Feb. 3, 2009, 2009 CPD ¶ 39 at 6.
Edmond Scientific Company (Edmond), of Chantilly, Virginia protests the decision by the Department of the Army, Medical Research Acquisition Activity, not to set aside for small businesses a task order proposal request (TOPR) No. TOPR 14MC22318, issued under a multiple-award, indefinite-delivery/indefinite-quantity (ID/IQ) contract for a variety of business-process and other support services. The protester argues that the Army’s decision not to reserve this task order for small business participation lacked a reasonable basis, was an abuse of discretion, and violated Federal Acquisition Regulation (FAR) § 19.502-2(b), the so-called “Rule of Two.” [1]
One application of beam expanders is in tunable laser resonates. Here an intracavity beam expander is used to increase the diameter of the laser beam to illuminate the width of a given diffraction grating. The beam divergence is reduced, and very narrow line widths can be emitted.
A Galilean telescope consists of one lens with a negative focal length (the objective) and another with a positive focal length (the image lens). These two lenses are also placed so the distance between them is equal to the sum of their focal lengths. As one of the lenses is negative, the objective and lens will be close together, and there will be no internal foci. This makes Galilean beam expanders a good choice of high-power laser applications, as there is no problem with high power density within the system.
[3] The protester also asserts that it expects its price will exceed the $10 million threshold and that this fact should be considered in addition to the Army’s IGE. Comments at 7, 8. We note that the agency has suspended the TOPR pending our resolution of this pre-closing protest, and therefore, has not yet received proposals. AR, Tab 15, TOPR amend. 4. Accordingly, we cannot rely on the value of submitted proposals to determine the value of the task order. See ICI Servs., Inc., B-409231.2, Apr. 23, 2014, 2014 CPD ¶ 132 at 3 n.3 (considering value of offerors’ submitted proposals for purposes of determining GAO jurisdiction).
Multi-prism beam expanders are formed from two to five prisms arranged to form an optical system with the desired properties. These prism beam expanders can be described by ray transfer matrices, and the generalized mathematical description is known as multi-prism dispersion theory.
Edmond is mistaken. Our Office has determined that the value of a task order may include the value of options, including an option to extend services under FAR clause 52.217-8, when the value of the option (if exercised) is evident from the face of the solicitation. Serco Inc., B-406061, B-406061.2, Feb. 1, 2012, 2012 CPD ¶ 61 at 6-7. While the TOPR here required contractors to submit prices for the base period and option periods 1-4, it did not require submission of prices that would be used if the Army exercised its option to extend services under FAR clause 52.217-8, nor did it provide any formula for calculating these prices.[2] In this regard, Edmond’s reliance on the TOPR’s statement that “the total evaluated price for orders would include all priced line items for the base year and all option periods” is misplaced, since the option-to-extend period here is not to be priced in proposals nor included in the evaluation of proposals.
